01

What was the context?

The Conservatives had governed for 14 years and changed prime minister three times during the Parliament. The opposition vote was split across Labour, Liberal Democrats, Reform UK, Greens and nationalist parties.

02

What happened?

Labour won 411 seats, the Conservatives 121 and the Liberal Democrats 72. Reform won five seats despite a larger UK vote share than the Liberal Democrats, another sharp illustration of geographic efficiency under first past the post.

03

Was it a shock?

A Labour majority was expected. The Conservatives' record-low seat total and the precise distribution of a fragmented vote gave the result its historic scale.

1832

THE REFORMED ELECTORAL ERA

Where this archive begins

The 1832 general election was the first after the Great Reform Act. Parliament's archive records 401 constituency contests returning 658 MPs, with multi-member seats, public voting and many uncontested returns. Party labels were fluid, so Road to 326 does not force that result into a modern two-party swing or a present-day boundary map.

READ THE CHARTS HONESTLY

Historic constituencies are not today's constituencies.

The Commons Library identifies major boundary breaks after reviews in 1945, 1948, 1955, 1974, 1983, 1997, 2005 in Scotland, 2010 elsewhere and again for 2024. Before 1950, some constituencies returned more than one MP; university seats and uncontested returns add further complications.

That is why the interactive result uses an equal-seat field: every returned MP is visible, but old votes are not painted onto new geography. Vote shares and grouped seat totals follow the source conventions stated for each election.

HISTORIC UK ELECTION FAQ

How to compare elections across time

What was the biggest UK general election landslide?

The answer depends on the measure and party grouping. The 1931 National Government returned an exceptionally dominant bloc; Labour's 418 seats in 1997 remain the largest number won by a single party; and the 1906 Liberals and allies held a 129-seat majority.

Why does the number of constituencies change between elections?

Parliamentary boundary reviews, the changing constitutional position of Ireland, university seats and historic multi-member constituencies all changed the size and shape of the House of Commons. The selected elections on this page range from 615 to 707 seats before settling at 650 in the modern era.

Why not put every historic result on today's constituency map?

That would be misleading. Boundaries changed repeatedly, and many old constituencies have no one-to-one modern equivalent. Road to 326 uses one equal tile per MP for cross-era comparisons and reserves the current geographic map for elections fought on current boundaries.

What is electoral swing?

Two-party swing is half the change in the gap between two parties' vote shares from one election to the next. It is a useful national summary, but it does not describe every constituency and becomes less meaningful when party systems, coalitions or the franchise change.

Where do these historic election results come from?

The principal sources are the House of Commons Library's century-of-elections tables and constituency dataset, the UK Parliament general election archive, and the Commons Library's verified 2024 results publication.
