We know there will be an election on 12 December, but the outcome, in terms of parliamentary seats and who will form the next government, remains uncertain. Robert Hazell and Harrison Shaylor answer some of the key questions about what happens if the election creates another hung parliament.

With an increasingly volatile electorate, and uncertain forecasts in the polls, it is possible the 2019 election will result in another hung parliament. Although bookmakers currently have a Conservative majority as comfortably the most likely election result, and the Conservatives are currently polling around 11 points ahead of Labour, a hung parliament is by no means out of the question. It would be the third hung parliament in four general elections. This explains what lessons can be learned from our previous experience of hung parliaments at Westminster and around the world. It addresses questions such as how a new government is formed, how long formation of that government will take, what kinds of government might emerge, and what the most likely outcomes are.

How common are hung parliaments in other countries?

In most democracies across the world, single party majority governments are the exception. Whereas the ‘first-past-the-post’ (FPTP) voting system used in the UK has had the tendency to encourage adversarial two-party politics and majority government, this is far from a default setting. Proportional representation tends almost always to produce coalitions: many countries in Europe currently have a coalition government.

Recent years have shown that, even in countries using FPTP, hung parliaments can occur quite frequently. In Canada, whose parliament uses the same electoral system as Westminster, there were 10 minority governments in the 20th century. There have already been four since 2000, including the incumbent minority government led by Justin Trudeau, formed after the Liberals lost their majority in the October 2019 federal election.

What is the experience of hung parliaments at Westminster?

Westminster has more experience of hung parliaments than is generally recognised. There were 20 governments in Westminster in the 20th century: four were coalitions, and six were minority governments. But single party majority governments dominated after the Second World War. The 2010 coalition government was the first since 1945 and the product of the first hung parliament in 36 years. Since 2010, however, two out of three general elections have produced hung parliaments (and the fact that David Cameron’s Conservatives succeeded in obtaining an absolute majority in 2015 was a surprise).
