February 1974 United Kingdom general election
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 (301 total) but was seventeen short of an overall majority. The Conservative Party, led by incumbent Prime Minister Edward Heath, lost 28 seats (though it polled a higher share of the vote than Labour). That 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 so Wilson became Prime Minister for a second time, his first with a minority government. Wilson called another early election in September, which was held in October and resulted in a Labour majority. The February election was also the first general election to be held with the United Kingdom as a member state of the European Communities (EC), which was widely known as the "Common Market".

Its results saw Northern Ireland diverging heavily from the rest of the United Kingdom, with all twelve candidates elected being from local parties (eleven of them representing unionist parties) after the decision of the Ulster Unionists to withdraw support from the Conservative Party in protest over the Sunningdale Agreement. The Scottish National Party achieved significant success at the election by increasing its share of the popular vote in Scotland from 11% to 22%, and its number of MPs from one to seven. Plaid Cymru also succeeded for the first time in getting candidates elected at a general election in Wales (its sole previous seat was won at a by-election in 1966).
Although Heath's incumbent Conservative government polled the most votes by a small margin, the Conservatives were overtaken in terms of seats by Wilson's Labour Party because of a more efficiently distributed Labour vote. Ultimately, the decision by the seven Ulster Unionist MPs not to take the Conservative whip proved decisive in giving Labour a slim plurality of seats. The other four unionists elected were hardliners who were not affiliated with the UUP.
Both the Labour and the Conservative parties lost a considerable share of the popular vote, largely to the Liberal Party under Jeremy Thorpe's leadership, which polled two-and-a-half times its share of the vote in the previous election. However, even with over 6,000,000 votes, only 14 Liberal MPs were elected. There had been some media projections that the Liberals could take twice as many seats.[1]
Given that it was not obvious who could command the support of the House, Heath did not resign immediately as Prime Minister. However, he knew that even if he could persuade all eleven of Northern Ireland's unionist MPs to support a Conservative government, at least on confidence matters, over one led by Wilson, he would still need the support of the Liberals to have a workable majority. Heath, therefore, started negotiations with Thorpe to form a coalition government. Thorpe, never enthusiastic about supporting the Conservatives, demanded major electoral reforms in exchange for such an agreement. Unwilling to accept such terms, Heath resigned, and Wilson returned for his second stint as Prime Minister.
The election night was covered live on the BBC and was presented by Alastair Burnet, David Butler, Robert McKenzie and Robin Day.[1][2]
Prominent members of Parliament who retired or were defeated at the election included Gordon Campbell, Bernadette McAliskey, Enoch Powell, Richard Crossman, Tom Driberg and Patrick Gordon Walker. It was the first of two United Kingdom general elections held that year, the first to take place after the United Kingdom became a member of the European Communities on 1 January 1973 and the first since 1929 not to produce an overall majority in the House of Commons for the party with the most votes. This was also the first time since 1910 that two general elections were held in the same year.
Economic background[edit]
It was the first general election in the United Kingdom to be held during an economic crisis since the 1931 general election, which had been held in the depths of the Great Depression.[11]
