David Cameron is a British politician who served as the Prime Minister of the United Kingdom from 2010 to 2016. He was the leader of the Conservative Party and became the youngest Prime Minister in nearly 200 years when he took office at the age of 43. Cameron's government focused on reducing the national deficit and implementing austerity measures. During his time in office, Cameron also oversaw significant events such as the Scottish Independence Referendum in 2014 and the Brexit referendum in 2016, where the UK voted to leave the European Union. He resigned shortly after the Brexit vote, leading to a change in leadership within the Conservative Party.
