The 2010s in the United Kingdom's political history were filled with lots of changes and events. The first big event was in 2010 when a new Prime Minister, David Cameron, was elected. Cameron was the leader of the Conservative Party, and his term in office lasted until 2016. During his time in power, he proposed a number of big changes to the UK, such as holding an 'in or out' referendum on the UK's membership of the European Union (EU). This referendum, known as the Brexit referendum, took place in 2016 and resulted in the UK voting to leave the EU.
Cameron stepped down from office in 2016 and was replaced by Theresa May as prime minister. May remained in power until 2019, when she resigned after failing to get Parliament to approve her Brexit deal. In 2019, Boris Johnson was elected as the new prime minister. Johnson is a member of the Conservative Party and during his time in office he has focused on getting Brexit done and the election of a new Brexit trade deal with the EU.
The UK's political landscape has also seen a lot of changes during the 2010s. The Conservative Party has remained the biggest political party in the UK, but smaller parties like the Liberal Democrats, Greens, and UKIP have also seen an increase in support. In addition, the political issue of Scottish independence has become more prominent, with more and more people in Scotland supporting the idea of an independent Scotland.
