Key takeaways
- Three election case studies are required: one from 1945–92, the compulsory 1997 election, and one since 1997. Each needs results, impact on parties and government, and the factors behind the outcome.
- In 1979 the Conservatives won 339 seats on 43.9% of the vote, a majority of 43, after the Winter of Discontent and a lost confidence vote by 311 to 310. It began 18 years of Conservative government.
- In 1997 Labour won 418 seats on 43.2% of the vote, a majority of 179, on a 10.2-point swing. The Conservatives were left with 165 seats and none at all in Scotland or Wales.
- In 2024 Labour won 411 seats and a majority of 174 on 33.7% of the vote and 59.7% turnout — 63.2% of seats from a third of the votes, which Sir John Curtice called the most disproportional ever.
- All three were turning-point elections in which a governing party lost its reputation for competence; leadership, manifesto, campaign and wider context then decided the scale of the defeat.

Key terms
- Swing
- The average movement of support from one party to another between two elections, measured in percentage points and used to compare results across constituencies.
- Landslide
- An election victory producing a very large parliamentary majority, well beyond what the winning party needs to govern securely.
- Governing competency
- Voters' judgement of how capably a party runs the country, or would run it from opposition — assessed on delivery and results rather than on ideology.
- Manifesto
- The document a party publishes before an election setting out the policies it undertakes to carry out if it wins.
- Mandate
- The authority a winning party claims to enact the programme it stood on, together with permission to decide issues that arise afterwards.
- Tactical voting
- Backing whichever candidate is best placed to defeat a party you oppose, rather than the candidate you would most like to win.
- Turning-point election
- An election that ends one period of party dominance and sets the direction of government for years afterwards, rather than simply returning the incumbent.
Frequently asked questions
One from 1945–92, the 1997 election, which is compulsory, and one since 1997. A common and well-evidenced choice is 1979, 1997 and 2024, because each ended a long period of one-party government and each is richly documented.
Labour's vote was spread efficiently across constituencies while the anti-Labour vote split between the Conservatives and Reform UK. Under first past the post, Labour took 63.2% of seats on 33.7% of the vote, with turnout at 59.7%.
The Winter of Discontent strikes destroyed Labour's claim to manage the economy and the unions; the Callaghan government then lost a confidence vote by 311 to 310. Conservative policy on tax, union law and council house sales attracted skilled working-class voters.
