The Labour Party, led by Keir Starmer, wins a landslide majority in the 2024 United Kingdom general election, ending 14 years of Conservative government.

The Labour Party, often referred to as Labour, is a political party in the United Kingdom that sits on the centre-left of the political spectrum. The party has been described as an alliance of social democrats, democratic socialists and trade unionists. It is one of the two dominant political parties in the United Kingdom; the other being the Conservative Party. Labour has been led by Keir Starmer since 2020, who became Prime Minister of the United Kingdom following the 2024 general election. To date, there have been 12 Labour governments and seven different Labour Prime Ministers – MacDonald, Attlee, Wilson, Callaghan, Blair, Brown and Starmer.

Sir Keir Rodney Starmer is a British politician and lawyer who has served as Prime Minister of the United Kingdom since 2024 and as Leader of the Labour Party since 2020. He previously served as Leader of the Opposition from 2020 to 2024. He has been Member of Parliament (MP) for Holborn and St Pancras since 2015, and was Director of Public Prosecutions from 2008 to 2013.

A landslide victory is an election result in which the winning candidate or party achieves a decisive victory by an overwhelming margin, securing a very large majority of votes or seats far beyond the typical competitive outcome. The term became popular in the 1800s to describe a victory in which the opposition is "buried", similar to the way in which a geological landslide buries whatever is in its path. A landslide victory for one party is often accompanied by an electoral wipeout for the opposition, as the overwhelming support for the winning side inflicts a decisive loss on its rivals. What qualifies as a landslide victory can vary depending on the type of electoral system, as the term does not entail a precise, technical, or universally agreed-upon measurement. Instead, it is used informally in everyday language, making it subject to interpretation. Even within a single electoral system, there is no consensus on the exact margin that constitutes a landslide victory.
