1979 United Kingdom general election

Conservatives win the 1979 United Kingdom general election

The election happened at all because Callaghan’s government had lost a confidence vote by a single MP, 311 to 310.

Thursday, 3 May 1979

Voters went to the polls in all 635 House of Commons constituencies on 3 May 1979. A record 2,576 candidates stood.

Margaret Thatcher’s Conservatives took about 43.9 percent of votes cast and 339 seats — an overall majority of 43, meaning 43 more seats than every other party combined. Nineteen women were elected to the 635-member Commons.

How the election was forced

On 28 March, James Callaghan’s government lost a Commons no-confidence motion 311–310. He announced the next day that he would request dissolution — the formal dissolution followed on 7 April — and polling was set for 3 May.

Among the newcomers elected was John Major, who won Huntingdonshire for the Conservatives.

Polling day was not accession day

British voters elected MPs, not a prime minister. Callaghan stayed in office overnight and resigned the following day; Queen Elizabeth II appointed Thatcher on 4 May, and she announced her Cabinet on 5 May.

The result did not end eighteen years of Labour rule — the Conservatives had governed from 1970 to 1974. It began eighteen consecutive years of Conservative government.
