How it works
The United Kingdom uses First Past the Post for general elections. The country is divided into 650 constituencies. In each, whoever gets the most votes wins — even if that is 25% with a four-way split. The party that wins the most seats forms the government.
What FPTP produces
FPTP consistently delivers majority governments. A single party with 40% of the popular vote can win 55% of seats, enabling a stable government. Critics point out the corollary: a party with 36% of votes can form a majority government, leaving 64% of voters represented by a government they did not support.
The case for reform
Advocates of proportional representation point to Germany, New Zealand and the Nordic countries as evidence that PR systems can deliver stable, effective government while more accurately translating votes into seats. Defenders of FPTP argue that strong local representation and the ability to vote out governments decisively are worth the trade-off in proportionality.
