South West Norfolk in the 2024 United Kingdom general election

An election took place in the East Angliaconstituency of South West Norfolk on 4 July 2024, as part of the 2024 general election. Liz Truss, the shortest-serving British prime minister in history, was standing for re-election as MP. On 2 July, in anticipation of a large Labour victory in the general election, a national poll of voters by Portland Communications had shown that Truss was the Conservative politician the highest percentage of people (28%) wanted to see lose their seat.

Suffering from both a reduction in popular support and from vote splitting with Reform UK candidate Toby McKenzie and independent James Bagge, Truss lost her seat with a 43.7% fall in the Conservative vote share, despite having won 69% of the vote at the previous election; The Spectator labelled the result the "Portillo moment" of the year.
