Who is the United Kingdom's prime minister as of July 2019?

Alexander Boris de Pfeffel Johnson (born 19 June 1964) is a British politician serving as Prime Minister of the United Kingdom and Leader of the Conservative Party since July 2019. He has been the Member of Parliament (MP) for Uxbridge and South Ruislip since 2015 and was the MP for Henley from 2001 to 2008. He also served as Mayor of London from 2008 to 2016 and Foreign Secretary from 2016 to 2018. Johnson identifies as a one-nation conservative and has been associated with both economically and socially liberal policies.

Born in New York City to wealthy English parents, Johnson was educated at the European School, Brussels I, Ashdown House, and Eton College. He read Classics at Balliol College, Oxford, where he was elected President of the Oxford Union in 1986. He began his career in journalism at The Times but was dismissed for falsifying a quotation. He later became The Daily Telegraph's Brussels correspondent, with his articles exerting a strong influence on growing Eurosceptic sentiment among the British right-wing. He was assistant editor of the Telegraph from 1994 to 1999, and edited The Spectator from 1999 to 2005. He was elected MP for Henley in 2001, and served in the Shadow Cabinet under Conservative leaders Michael Howard and David Cameron. He largely adhered to the Conservatives' party line but adopted a more socially liberal stance on issues such as LGBT rights in parliamentary votes.
