The Conservative Party, officially the Conservative and Unionist Party, is a centre-right political party in the United Kingdom. It is currently the governing party, having been so since the 2010 general election, where a coalition government with the Liberal Democrats was formed. In 2015, the Conservatives led by David Cameron won a surprise majority and formed the first Conservative majority government since 1992. However, the snap election on 8 June 2017 resulted in a hung parliament, and the party lost its parliamentary majority. It is reliant on the support of a Northern Irish political party, the Democratic Unionist Party (DUP), in order to command a majority in the House of Commons through a confidence-and-supply deal. The party leader, Theresa May, has served as both Leader of the Conservative Party and Prime Minister since July 2016. It is the largest party in local government with 9,116 councillors. The Conservative Party is one of the two major contemporary political parties in the United Kingdom, the other being its modern rival, the Labour Party.
