The nutshell

One person wins per place. Whoever gets the most votes is the winner — even if most people voted for someone else.

Sam wins the seat. Priya and Jo’s 62 votes get nothing.

The basics

How it works

The UK is split into 650 areas called constituencies. Each one sends one MP to Parliament.EC

On election day, each voter puts one X next to one name. The candidate with the most votes in that area wins the seat. There is no prize for second place.

Why the UK uses it

It’s simple to use and fast to count. It usually gives one party enough seats to run the government on its own.HoC The UK has used it for elections to Parliament for over a century.

The catch: wasted votes

Every vote for a losing candidate — and every extra vote for the winner beyond what was needed — changes nothing. In the 2024 general election, most votes were like this (Electoral Reform Society).ERS

The dotted line is the thread that never gets pulled — those votes made no difference to the result.

Compared to other systems

Other countries share seats out to match the votes — that’s called Proportional Representation. Some systems rank candidates in order, like the Alternative Vote.

What supporters say
  • Simple — one X, one winner
  • Fast, clear results by morning
  • Each area gets one local MP
What critics say
  • Seats don’t match how people voted
  • Millions of votes change nothing
  • Smaller parties find it hard to win seats
Got it?
Three quick questions. Nothing is saved.
1. How many MPs does each constituency send to Parliament?
2. To win a seat, a candidate needs…
3. True or false: votes for losing candidates still help elect someone.

Votes vs seats in 2024

FPTP can produce big gaps between vote share and seat share. The 2024 general election was the starkest on record.HoC

Party colours follow the standard used in election results tables.

Who wants to change it

As a pattern, parties that win lots of seats under FPTP tend to keep supporting it, and parties that win a smaller share of seats than of votes tend to want change. The Liberal Democrats, Greens and Reform UK have all called for proportional systems. Labour and the Conservatives have kept FPTP for Westminster while in government.

Scotland, Wales and Northern Ireland already use different, more proportional systems for the devolved parliaments and assemblies.

How the UK got here

FPTP wasn’t designed — it grew out of medieval practice, when counties simply sent whoever the most people backed. The secret ballot arrived in 1872, and every adult finally got the vote in 1928.

In 2011 the UK held a referendum on switching to the Alternative Vote. About 68% voted to keep FPTP, on a low turnout.Parl
