Landslide Victory

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 is the opposite of an electoral wipeout; a party which wins in a landslide typically inflicts a wipeout on its opposition.

What constitutes a landslide varies by the type of electoral system. Even within an electoral system, there is no consensus on what sized margin makes for a landslide.

United Kingdom

 

 

 

In UK General Elections, a landslide victory involves winning a large majority in parliament and often goes with a large swing from one party to another as well. Landslide victories have usually occurred after a long period of government from one particular party and a change in the popular mood. In the past a majority of over 100 was regarded as the technical hurdle to be defined as a landslide, as that allows the government freedom to easily enact its policies in parliament. In more recent times, the label 'landslide' has been applied in numerous press articles to victories which would not previously have been regarded as such, for example the Conservative Party majority of 80 in 2019. Its current usage is more as political commentary rather than technical definition and is a reflection of the strength of the party's ability to put its program through parliament.

The largest landslide by any single party in the UK parliament, since universal suffrage was introduced, was the majority of 179 won by Tony Blair's Labour Party in 1997.
