The 1929 United Kingdom general election was held on Thursday, 30 May 1929 and resulted in a hung parliament. Ramsay MacDonald's Labour Party won the most seats in the House of Commons for the first time. The Liberal Party led again by former Prime Minister David Lloyd George regained some ground lost in the 1924 general election and held the balance of power. Parliament was dissolved on 10 May. 
The election was often referred to as the "Flapper Election", because it was the first in which women aged 21–29 had the right to vote (owing to the Representation of the People Act 1928). (Women over 30 had been able to vote since the 1918 general election.)
The election was fought against a background of rising unemployment, with the memory of the 1926 general strike still fresh in voters' minds. By 1929, the Cabinet was being described by many as "old and exhausted". 
The Liberals campaigned on a comprehensive programme of public works under the title "We Can Conquer Unemployment". There was anticipation of a potential revival of the Liberal Party after the reunification of Independent Liberals and National Liberals under Lloyd George's leadership in 1928 and following some victories in a series of by-elections after 1926.  The incumbent Conservatives campaigned on the theme of "Safety First", with Labour campaigning on the theme of "Labour & the Nation".
This was the first general election to be contested by the newly formed Welsh nationalist party Plaid Cymru.
It stood as the last time when a third party polled more than one-fifth of the popular vote until 1983. The Liberals performed more successfully than at the previous general election in 1924, but could not regain its pre-World War I status as a party of government.  The next election thus ushered in five decades in which two-party politics dominated.

The 1997 United Kingdom general election was held on Thursday, 1 May 1997. The governing Conservative Party led by Prime Minister John Major was defeated in a landslide by the Labour Party led by Tony Blair, achieving a 179-seat majority.
The 1983 United Kingdom general election was held on Thursday 9 June 1983. It gave the Conservative Party under the leadership of Margaret Thatcher the most decisive election victory since that of the Labour Party in 1945, with a majority of 144 seats and the first of two consecutive landslide victories.
The 1992 United Kingdom general election was held on Thursday 9 April 1992, to elect 651 members to the House of Commons. The election resulted in the fourth consecutive victory for the Conservative Party since 1979 and would be the last time that the Conservatives would win an overall majority at a general election until 2015. It was also the last general election to be held on a day which did not coincide with any local elections until 2017. This election result took many by surprise, as opinion polling leading up to the election day had shown the Labour Party, under leader Neil Kinnock, consistently, if narrowly, ahead.
The 1987 United Kingdom general election was held on Thursday, 11 June 1987, to elect 650 members to the House of Commons. The election was the third consecutive general election victory for the Conservative Party, and second landslide under the leadership of Margaret Thatcher, who became the first Prime Minister since the Earl of Liverpool in 1820 to lead a party into three successive electoral victories.
The February 1974 United Kingdom general election was held on Thursday, 28 February 1974. The Labour Party, led by Leader of the Opposition and former Prime Minister Harold Wilson, gained 14 seats, but was seventeen short of an overall majority. The Conservative Party, led by incumbent Prime Minister Edward Heath, lost 28 seats; but achieved a higher share of the vote than Labour. This resulted in a hung parliament, the first since 1929. Heath sought a coalition with the Liberals, but the two parties failed to come to an agreement and then Wilson became Prime Minister for a second time, his first under a minority government. Because Labour was unable to form a majority coalition with another party, Wilson called another early election in September, which was held in October and resulted in a Labour majority. This was also the first general election to be held with the United Kingdom as a member state of the European Communities (EC)—widely known as the "Common Market".
The October 1974 United Kingdom general election took place on Thursday 10 October 1974 to elect 635 members of the British House of Commons. It was the second general election held that year, the first year that two general elections were held in the same year since 1910, and the first time that two general elections were held less than a year apart from each other since the 1923 and 1924 elections, which took place 10 months apart. The election resulted in the Labour Party led by Harold Wilson winning a bare majority of just 3 seats. This enabled the remainder of the Labour government, 1974–1979 to take place, which saw a gradual loss of its majority.
The 1945 United Kingdom general election was a national election held on 5 July 1945, but polling in some constituencies was delayed by some days, and the counting of votes was delayed until 26 July to provide time for overseas votes to be brought to Britain. The governing Conservative Party sought to maintain its position in Parliament but faced challenges from public opinion about the future of the United Kingdom in the post-war period. British Prime Minister Winston Churchill proposed to call for a general election in Parliament, which passed with a majority vote less than two months after the conclusion of the Second World War in Europe.
The 1964 United Kingdom general election was held on 15 October 1964, five years after the previous election, and thirteen years after the Conservative Party, first led by Winston Churchill, had regained power. It resulted in the Conservatives, led by the incumbent Prime Minister Alec Douglas-Home, narrowly losing to the Labour Party, led by Harold Wilson; Labour secured a parliamentary majority of four seats and ended its thirteen years in opposition. Wilson became the youngest Prime Minister since Lord Rosebery in 1894. To date, this is also the most narrow majority obtained in the House of Commons with just 1 seat clearing Labour for a majority government.
The 1950 United Kingdom general election was the first ever to be held after a full term of Labour government. The election was held on Thursday 23 February 1950, and was the first held following the abolition of plural voting and university constituencies. The government's 1945 lead over the Conservative Party shrank dramatically, and Labour was returned to power but with an overall majority reduced from 146 to just 5. There was a 2.8% national swing towards the Conservatives, who gained 90 seats. Labour called another general election in 1951, which the Conservative Party won.
The 1951 United Kingdom general election was held twenty months after the 1950 general election, which the Labour Party had won with a slim majority of just five seats. The Labour government called a snap election for Thursday 25 October 1951 in the hope of increasing its parliamentary majority. However, despite winning the popular vote and achieving both the highest-ever total vote and highest percentage vote share, Labour won fewer seats than the Conservative Party. This was mainly due to the collapse of the Liberal vote, which enabled the Conservatives to win seats by default. The election marked the return of Winston Churchill as Prime Minister, and the beginning of Labour's thirteen-year spell in opposition. This was the third and final general election to be held during the reign of King George VI, as he died the following year on 6 February and was succeeded by his daughter, Elizabeth II. It was the last election in which the Conservatives did better in Scotland than in England.
The 1955 United Kingdom general election was held on Thursday 26 May 1955, four years after the previous general election in 1951. It was a snap election: after Winston Churchill retired in April 1955, Anthony Eden took over and immediately called the election in order to gain a mandate for his government. It resulted in a majority of 60 seats for the government under new leader and Prime Minister Anthony Eden; the result remains the largest party share of the vote at a post-war general election. This was the first general election to be held with Elizabeth II as monarch. She had succeeded her father George VI a year after the previous election.
The 1959 United Kingdom general election was held on Thursday, 8 October 1959. It marked a third consecutive victory for the ruling Conservative Party, now led by Harold Macmillan. For the second time in a row, the Conservatives increased their overall majority in Parliament, this time to a landslide majority of 100 seats, having gained 20 seats for a return of 365. The Labour Party, led by Hugh Gaitskell, lost 19 seats and returned 258. The Liberal Party, led by Jo Grimond, again returned only six MPs to the House of Commons, but managed to increase its overall share of the vote to 5.9%, compared to just 2.7% four years earlier.
The 1935 United Kingdom general election was held on Thursday 14 November 1935 and resulted in a large, albeit reduced, majority for the National Government now led by Stanley Baldwin of the Conservative Party. The greatest number of members, as before, were Conservatives, while the National Liberal vote held steady. The much smaller National Labour vote also held steady but the resurgence in the main Labour vote caused over a third of their MPs, including National Labour leader Ramsay MacDonald, to lose their seats.
The 1931 United Kingdom general election was held on Tuesday 27 October 1931 and saw a landslide election victory for the National Government which had been formed two months previously after the collapse of the second Labour government. Collectively, the parties forming the National Government won 67% of the votes and 554 seats out of 615. The bulk of the National Government's support came from the Conservative Party, and the Conservatives won 470 seats. The Labour Party suffered its greatest defeat, losing four out of every five seats compared with the previous election, including the seat of its leader Arthur Henderson. Ivor Bulmer-Thomas said the results "were the most astonishing in the history of the British party system". It is the most recent election in which one party received an absolute majority of the votes cast, and the last UK general election not to take place on a Thursday. It would be the last election until 1997 in which a party won over 400 seats in the House of Commons.
The 1924 United Kingdom general election was held on Wednesday 29 October 1924, as a result of the defeat of the Labour minority government, led by Ramsay MacDonald, in the House of Commons on a motion of no confidence. It was the third general election to be held in less than two years. Parliament was dissolved on 9 October.
The 1923 United Kingdom general election was held on Thursday 6 December 1923. The Conservatives, led by Stanley Baldwin, won the most seats, but Labour, led by Ramsay MacDonald, and H. H. Asquith's reunited Liberal Party gained enough seats to produce a hung parliament. It is the most recent UK general election in which a third party won over 100 seats. The Liberals' percentage of the vote, 29.7%, has not been exceeded by a third party at any general election since.
The 1922 United Kingdom general election was held on Wednesday 15 November 1922. It was won by the Conservative Party, led by Bonar Law, which gained an overall majority over the Labour Party, led by J. R. Clynes, and a divided Liberal Party.
The 1918 United Kingdom general election was called immediately after the Armistice with Germany which ended the First World War, and was held on Saturday, 14 December 1918. The governing coalition, under Prime Minister David Lloyd George, sent letters of endorsement to candidates who supported the coalition government. These were nicknamed "Coalition Coupons", and led to the election being known as the "coupon election". The result was a massive landslide in favour of the coalition, comprising primarily the Conservatives and Coalition Liberals, with massive losses for Liberals who were not endorsed. Nearly all the Liberal MPs without coupons were defeated, including party leader H. H. Asquith.
The 2005 United Kingdom general election was held on Thursday 5 May 2005, to elect 646 members to the House of Commons. The Labour Party, led by Tony Blair, won its third consecutive victory, with Blair becoming the second Labour leader after Harold Wilson to form three majority governments. However, its majority fell to 66 seats compared to the 167-seat majority it had won four years before. This was the first time the Labour Party had won a third consecutive election, and remains the party's most recent general election victory.
The 1928 Middlesbrough West by-election was a parliamentary by-election held for the British House of Commons constituency of Middlesbrough West on 7 March 1928.
