United Kingdom by-election records

From Wikipedia, the free encyclopedia

UK by-election records is an annotated list of notable records from United Kingdom by-elections. A by-election occurs when a Member of Parliament resigns, dies, or is disqualified or expelled, and an election is held to fill the vacant seat. A constituency is the seat or division that member represented.

Prior to 1945, electoral competition in the United Kingdom exhibited features which make meaningful comparisons with modern results difficult.

Among the most significant were:-

• Frequent interventions and withdrawals of parties in different seats.
• Frequent Coalitions between parties, splits within parties and floor-crossing by members.
• Uncontested elections and truces between parties, in particular during both World Wars.
• Generally more significant competition from independent candidates and minor parties.
• Multi-member seats and University seats.
• Higher frequency of by-elections.
• Generally higher turnouts, although several wartime elections exhibited the lowest recorded turnouts.
• Generally higher variation in size of constituency electorates.

Since 1945, the evolution of a stable 3-party system has tended to negate each of the above features so that, broadly speaking, elections are more comparable.

In Northern Ireland, as ever, the pattern of party competition is completely different to that on the mainland and comparisons remain problematic.

Hence, unless otherwise stated records are based on results since the 1945 General Election, and earlier exceptional results are listed separately.

For comparison purposes the following definitions have been adopted.

• Gain - victory by a party which was not victorious at the immediate previous election.
• Loss - defeat of a party which was victorious at the immediate previous election.
• Hold - victory by a party which was victorious at the immediate previous election.
• Win - victory by a party. Ambiguous term that could mean either a gain or a hold.
• Incumbent - the party which held the seat at the immediate previous election, irrespective of any intervening change of candidate or candidate's change of party.
• Third Party - In England, since 1922, the "third party" has been the Liberal party and its successors up to the present day Liberal Democrats. Additionally, in Scotland and Wales the Scottish National Party and Plaid Cymru are also considered to be Third Parties. Prior to 1922, the third party was the Labour party.
• Minor Party - parties smaller than the Third Party
• Uncontested - an election where only one candidate is put forward. No votes are actually cast and the candidate is by definition the victor.

[edit] Most candidates

Any number of candidates can be nominated for election under current UK electoral law. There are no restrictions, with the only required stipulation (other than residency rules) being the valid nomination of ten electors from the constituency. By-elections often attract "fringe" or novelty candidates, single-issue candidates, or independents. As with nominations in a general election, candidates must pay a £500 deposit which is only refunded if the candidate wins 5% of the votes cast.

All by-elections with more than ten candidates are listed. Those which created a new record number are shown in bold.

• 19: Newbury by-election, 1993
• 18: Kensington and Chelsea by-election, 1999

This beat the long-standing record of seven who contested the Stockport by-election, 1920, where two seats were available, and was first reached in a single-member by-election in the South Dorset by-election, 1962. This in turn beat the six candidates who stood in the Glasgow Camlachie by-election, 1948.

[edit] Candidate records

[edit] Durable by-election candidates

Former Labour cabinet minister Tony Benn contested no fewer than four by-elections during his career, topping the poll on each occasion: Bristol South East in 1950, Bristol South East in 1961, Bristol South East in 1963 and Chesterfield in 1984. His first and last by-election victories were 33 years and 3 months apart.

Former cabinet minister and European Commissioner Roy Jenkins fought two different by-elections for the SDP only eight months apart. He narrowly failed in the Warrington by-election, 1981 before winning the Glasgow Hillhead by-election, 1982. He had been first elected as a Labour MP almost 34 years previously in the Southwark Central by-election, 1948.

Former Speaker of the House of Commons, Betty Boothroyd finally secured election at her third by-election attempt at the West Bromwich by-election, 1973. She had previously failed in the Leicester South East by-election, 1957 and the Nelson and Colne by-election, 1968 as well as the General Elections of 1959 and 1970.

Arthur Henderson was distinguished in being successful in no fewer than five by-elections in different seats, in Barnard Castle, Widnes, Newcastle-upon-Tyne East, Burnley, and Clay Cross.

Joseph Gibbins is the only person in modern times to gain the same seat twice in two different by-elections. He triumphed for Labour in the Liverpool West Toxteth by-election, 1924 and the Liverpool West Toxteth by-election, 1935.

William O'Brien won four by-elections, in Mallow in 1883, North East Cork in 1887 and then Cork City in 1904 and 1914. On these last two occasions, he was re-elected having resigned the seat.

Prime Minister Winston Churchill contested five by-elections in his long career:-

• Oldham by-election, 1899 in which he was not elected
• Manchester North-West by-election, 1908 where he was defeated
• Dundee by-election, 1908 where he was elected
• Dundee by-election, 1917 where he was re-elected unopposed
• Westminster, Abbey by-election, 1924 in which he was unsuccessful

John Wilkes won the Aylesbury by-election, 1757, and was then elected in the Middlesex by-elections of February, March and April 1769, on each occasion being subsequently expelled from the House of Commons.

[edit] Oldest by-election victors

• Enoch Powell was 73 when he successfully defended his seat at the South Down by-election, 1986, although he had been an MP almost continuously since 1950.
• Arthur Salter was 70 when he held the Ormskirk by-election, 1951 for the Conservatives. He had served previously as MP for Oxford University 1937-50.
• John Evans was 70 when he held the Ogmore by-election, 1946 for Labour.
• David Hardie, the half-brother of Keir Hardie, was thought to be about 70 when he held the Glasgow Rutherglen by-election, 1931 for Labour.
• George Edwards was almost 70 when he gained the South Norfolk by-election, 1920 for Labour. He was an agricultural labourer, and was so poor that his Conservative opponent lent him a suit to allow him to take his seat in the House of Commons.

[edit] First women by-election victors

The first woman to be elected in a by-election was Nancy Astor, who succeeded her husband at the Plymouth Sutton by-election, 1919, becoming the first woman to take her seat in the House of Commons.

The first woman to gain a seat in a by-election was Susan Lawrence who won the East Ham North by-election, 1926, although she had previously sat for the same seat between 1923-4.¹

The first woman to gain a seat ab initio in a by-election was Jennie Lee who won the North Lanarkshire by-election, 1929, at the same time becoming the first woman Baby of the House of Commons.

Note ¹Mabel Philipson succeeded her husband at the Berwick-upon-Tweed by-election, 1923. He had been elected as a National Liberal. She won as a Conservative so this could arguably be classed as the first gain by a woman.

[edit] First ethnic minority by-election victors

Whilst the first ethnic minority Members of Parliament were elected as early as the 1890s, it would be almost 100 years before one was returned at a by-election.

The first ethnic minority candidate to be elected in a by-election was Ashok Kumar who gained the Langbaurgh by-election, 1991 for Labour.

David Lammy held the Tottenham by-election, 2000 for Labour.

Mark Hendrick held the Preston by-election, 2000 for Labour.

Parmjit Singh Gill gained the Leicester South by-election, 2004 for the Liberal Democrats.

[edit] Frequency and duration records

[edit] Longest period without a by-election

All periods of over a year between by-elections are listed:

• 20 November 1997 - 10 June 1999: 567 days
• 7 November 1991 - 6 May 1993: 546 days
• 12 March 1987 - 14 July 1988: 489 days
• 14 February 2002 - 18 June 2003: 489 days
• 23 May 1974 - 26 June 1975: 399 days
• 18 June 2003 - 15 July 2004: 393 days

Notes. 1992 and 1998 are the only calendar years in history without a single by-election. Since 1992 was nonetheless a General Election year, 1998 stands as the only year in British history without any parliamentary election.

[edit] Longest period without a seat changing hands

The longest period without a seat changing hands in a by-election was the 5 years between the Conservative victories in the Glasgow Camlachie by-election, 1948 and the Sunderland South by-election, 1953.

During the short Parliaments of 1910, 1950-1 and 1974 no seats changed hands in a by-election.

[edit] Longest period between by-election gains for a party

The Liberal Party endured 29 years without a single by-election gain between the Holland and Boston by-election, 1929 and the Torrington by-election, 1958. It did not win a single by-election in the thirteen years between holding the Middlesbrough West by-election, 1945 and gaining Torrington.

As of early 2007, the opposition Conservative Party has not gained a seat in almost 25 years, the last being the Mitcham and Morden by-election, 1982 which occurred during the unique cirmcumstances of the Falklands War. Its last gain while in Opposition was 29 years ago at the Ilford North by-election, 1978.

Labour's longest lean stretch was almost 18 years, between gaining the Brecon and Radnor by-election, 1939 and the Lewisham North by-election, 1957.¹

Note ¹ The Labour Party were the official opposition in the Parliament elected in 1935, but after the major parties agreed an electoral truce on the outbreak of war in 1939, they did not contest any Conservative or Liberal seats for the remainder of the Parliament, a period of six years, and were members of the wartime coalition government between May 1940 and May 1945.

[edit] Longest period between by-election holds for a party

The Conservatives did not successfully defend a single by-election in the eight years between their holds of the Richmond by-election, 1989 and the Uxbridge by-election, 1997, losing a record 15 consecutive seats where it was the incumbent.

Labour's worst run was in losing 4 by-elections on the trot, which has occurred three times since 1945:

between holding the Newcastle-upon-Tyne Central by-election, 1976 and the Grimsby by-election, 1977.

between holding the Manchester Gorton by-election, 1967 and the Sheffield Brightside by-election, 1968.

between holding the Rhondda West by-election, 1967 and the Manchester Gorton by-election, 1967.

[edit] Longest period without an opposition gain

Since the 1997 General Election, the principal opposition Conservative Party has failed to register a by-election gain against the incumbent Labour Government. This is the longest period of such failure since records began, and nearly twice the previous record of the 5 years it took the then Labour opposition to gain the Lewisham North by-election, 1957.

Apart from the brief parliaments of 1910, 1950-1 and 1974, the parliaments of 1951-5 and 1997-2001 are the only occasions when the Government did not lose a by-election.

[edit] Most by-elections in one day

The largest number of by-elections held on a single day occurred on 23 January 1986 when 15 simultaneous contests were held in Northern Ireland. The elections had been engineered by the incumbent Unionist parties as a protest against the Anglo-Irish Agreement of 1985. They intended the results to be interpreted as a referendum on the treaty. The elections were boycotted by the main Nationalist parties except in four seats where they had a reasonable prospect of victory. In the event, the Social Democratic and Labour Party gained one seat, Newry and Armagh, from the Ulster Unionist Party.

Apart from the above example, it is common for UK mainland parties to schedule several by-elections on the same day. Motivations include attempting to divide opponents' resources and getting bad news (expected losses) out of the way. Since 1945, the largest number of simultaneous mainland by-elections has been 6, held on 16 November 1960. On four occasions, 5 by-elections have been held on the same day, most recently on 9 June 1994. Groupings of two or three are very common.

[edit] Most by-election losses in one day

The largest number of by-elections lost on a single day is three, when the Labour party lost Acton, Dudley and Meriden on 28 March 1968.

Occasions since 1945 when two seats have fallen are:

• 7 November 1991

[edit] By-election days

Currently, all British Parliamentary elections are invariably held on a Thursday. The last by-election not held on a Thursday was the Hamilton by-election, 1978, held on Wednesday 31 May due to a World Cup opening match on the Thursday evening.

Due to an administrative oversight, the Manchester Exchange by-election, 1973 was held on Wednesday 27 June 1973. Prior to that, the last by-elections not held on a Thursday were the Saffron Walden by-election, 1965 held on Tuesday 23 March, and the Roxburgh, Selkirk and Peebles by-election, 1965 held the following day.

Until the mid-1960s, it was common to hold by-elections on any day of the week (other than Sunday).

[edit] Miscellaneous records

[edit] Incumbents fall directly from first place to third place

• Littleborough and Saddleworth by-election, 1995 Conservatives loss, gained by the Liberal Democrats
• Perth and Kinross by-election, 1995 Conservative loss, gained by the SNP
• Eastleigh by-election, 1994 Conservative loss, gained by the Liberal Democrats
• Brecon and Radnor by-election, 1985 Conservative loss, gained by the Liberals
• Mitcham and Morden by-election, 1982¹ Labour loss, gained by the Conservatives
• Rochdale by-election, 1958 Conservative loss, gained by Labour

• Bosworth by-election, 1927 Conservative loss, gained by the Liberals
• Hull Central by-election, 1926² Liberal loss, gained by Labour
• South Norfolk by-election, 1920 Liberal loss, gained by Labour

¹ Bruce Douglas-Mann had been re-elected as Labour MP for the seat in the 1979 General Election. In 1981, along with several other MPs, he defected to the newly-formed Social Democratic Party. Against his new colleagues' advice, he honoured a pledge to face his electors under his new party colours and precipitated a by-election. He came second in the by-election which was won by the Conservatives. The new Labour candidate finished third.

² the Liberal MP, Lt-Commander the Hon. Joseph Montague Kenworthy, defected to Labour and sought re-election under his new colours. He was successful, and the new Liberal candidate lost his deposit.

[edit] Incumbent Governments gain seats

These records show the rare occasions when the Government won a seat they had not won at the previous General election.

[edit] Conservative

• Mitcham and Morden by-election, 1982, from Labour
• Bristol South-East by-election, 1961¹, from Labour
• Brighouse and Spenborough by-election, 1960, from Labour
• Sunderland South by-election, 1953, from Labour
• Combined English Universities by-election, 1926, from the Liberals
• Hackney South by-election, 1922, from the Independent Parliamentary Group
• Woolwich East by-election, 1921, from Labour
• Stockport by-election, 1920, from Coalition Labour²

¹ Seat awarded by Election Court to Conservative runner-up because Labour victor deemed ineligible.

² An arguable gain; Stockport was a two-member seat; in the 1918 general election it was won by two supporters of the Coalition Government, one a Liberal and one a Labour member. After a death and a resignation, a by-election was held for both seats. The seats were again won by two Coalition Government supporters, but this time a Conservative and a Liberal, while a Labour candidate who did not support the government was unsuccessful.

[edit] By-election holds overturned at next general election

By-elections usually see the high-water mark of any challenge to the incumbents. On rare occasions a party has failed to overturn an incumbent in the by-election yet has gone on to gain the seat at the subsequent general election.

• South Down by-election, 1986, held by the Ulster Unionists; gained by the Social Democratic and Labour Party in 1987.
• Darlington by-election, 1983, held by Labour; gained by the Conservatives in 1983.
• Dundee East by-election, 1973, held by Labour; gained by the Scottish National Party in February 1974.
• Bolton East by-election, 1960, held by the Conservatives; gained by Labour in 1964.

[edit] By-election victors had not contested previous general election

It is unusual for a political party which has not contested a seat at a general election to take it at a subsequent by-election. Many of the parties which have done so were founded after the general election. Independent candidates are not included.

• Isle of Ely by-election, 1973, gained by the Liberals

[edit] Incumbent party did not contest

• North Down by-election, 1995 (party disintegrated before by-election)
• Bristol South East by-election, 1963 (Conservative candidate awarded seat after 1961 by-election had agreed to stand aside, if law changed to permit disqualified Labour candidate to take his seat)

The Conservative Party did not run a candidate in the Bristol South East by-election, 1963, the Carmarthen by-election 1957, the Paisley by-election, 1948 or the Ogmore by-election, 1946.

The Labour Party did not run in the City of London by-election, 1945, the Kensington South by-election, 1945 or the Combined English Universities by-election, 1946.

The last by-election without an official Liberal Democrat, Liberal or SDP candidate was the Newham North East by-election, 1994; the Lib Dems nominated a candidate, but he joined the Labour Party before the election. The last by-election in which no official Liberal candidate was nominated was the Glasgow Central by-election, 1980. The last such in England were the Westhoughton by-election, 1973 and the West Bromwich by-election, 1973, both held on 24 May 1973.

The last Scottish by-elections without official Scottish National Party candidates were the Roxburgh, Selkirk and Peebles by-election, 1965 and the Rutherglen by-election, 1964.

The last Welsh by-elections without official Welsh Nationalist candidates were the Abertillery by-election, 1950, the Pontypool by-election, 1946 and the Monmouth by-election, 1945.

[edit] Miscellaneous notable results

• The drop in the Conservative share of the vote, 11.1%, at the Bromley and Chislehurst by-election, 2006 was their worst result in a Conservative-held seat while in opposition since 1930¹. At the same by-election, the Labour Party's fall from second to fourth place was the first time the party had suffered such a reverse in an English seat.

• At the Blaenau Gwent by-election, 2006, held on the same day as Bromley, the Conservative Party's fifth-place ranking equalled the worst-place achieved by a major party in England or Wales, a feat the Conservatives had first achieved in the same seat in the 2005 General Election. The Blaenau by-election victor, Dai Davies was the first independent to hold a seat previously occupied by an independent since Sir C.V.F. Townshend held The Wrekin in 1920.

• The Conservative Party fell from second to fourth place in the Hartlepool by-election, 2004.

• The Labour party fell from second to fourth place in the Ceredigion by-election, 2000.

• In the Hamilton South by-election, 1999, the Liberal Democrats came sixth, equalling the worst ever placing by a major party in the UK.

• The Conservative party fell from third to fourth place in the Liverpool Walton by-election, 1991.

• At the Bootle by-election, 1990 the "continuing" SDP finished seventh out of eight candidates, behind the Monster Raving Loony Party, in a seat parts of which had once been in adjoining Crosby, scene of the party's greatest triumph only eight years previously.

• The Labour party achieved fourth place in the Richmond (Yorks) by-election, 1989 although this was contrived somewhat by the Liberal (SLD) and SDP parties running separate candidates.

• The Conservative party fell from second place to fourth place in the Bermondsey by-election, 1983, the first time they had suffered such a reverse since at least 1945.

• At the Walsall North by-election, 1976, the Liberal Party could take only fifth place. Beaten by an independent and a minor party candidate, this was the worst placing for any major party in an English by-election since at least 1945.

• The Conservative party fell from third place to fourth place in the Newham South by-election, 1974, at the time their worst ranking in an English by-election since at least 1945.

• The last time time the Liberals lost a by-election they were defending was at the Carmarthen by-election, 1957, defeated by the former Liberal MP turned Labour candidate, Lady Megan Lloyd-George. The Liberal parliamentary contingent was thus reduced to five MPs, its lowest ever level.

Notes ¹Excluding the Westminster, St.George's by-election, 1931 and the Paddington South by-election, 1930, which were essentially intra-Conservative contests, the previous worst result was, ironically, the Bromley by-election, 1930

• Newport by-election, 1922: Election of a Conservative in a marginal seat spurred on Conservative MPs to end their coalition with David Lloyd George.
