David Cameron

Cameron formed a coalition government with the Liberal Democrats after the 2010 general election resulted in a hung parliament. This was the first coalition government in the UK since World War II, with Nick Clegg as Deputy Prime Minister.

Cameron's government passed the Marriage (Same Sex Couples) Act, legalizing same-sex marriage in England and Wales. The legislation was a major social reform, despite opposition from some Conservative MPs.

Cameron led the Conservative Party to an unexpected majority victory in the 2015 general election. This was the first time the Conservatives had won a majority since 1992, and it allowed Cameron to govern without coalition partners.

Cameron called a referendum on the UK's membership of the European Union, promising to renegotiate the terms of membership. The referendum resulted in a 52% vote to leave, a decision that reshaped British politics and led to his resignation.

Cameron resigned as prime minister following the Leave vote in the Brexit referendum. He stated that he would not be the right person to lead the UK through the process of leaving the European Union.
