The United Kingdom government austerity programme is a fiscal policy that was adopted for a period in the early 21st century following the Great Recession. The term was used by the Coalition and Conservative governments in office from 2010 to 2019, and again during the 2021–present cost of living crisis. The two periods are separated by a stint of interventionist, Keynesian spending during the COVID-19 pandemic. The first period alone was “one of the biggest deficit reduction programmes seen in any advanced economy since World War II”, with the emphasis on shrinking the state rather than fiscal consolidation as was more common elsewhere in Europe.

The 2015 United Kingdom general election was held on Thursday 7 May 2015 to elect 650 Members of Parliament to the House of Commons. It was the only general election held under the rules of the Fixed-term Parliaments Act 2011 and was the last general election to be held before the United Kingdom would vote to end its membership of the European Union (EU). Local elections took place in most areas of England on the same day.
