<span class="mw-page-title-main">1950 United Kingdom general election</span>

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.

A safe seat is an electoral district (constituency) in a legislative body which is regarded as fully secure, for either a certain political party, or the incumbent representative personally or a combination of both. In such seats, there is very little chance of a seat changing hands because of the political leanings of the electorate in the constituency concerned and/or the popularity of the incumbent member. The opposite type of seat is a marginal seat. The phrase tantamount to election is often used to describe winning the dominant party's nomination for a safe seat.
