Sadiq Khan favorit i duell om att efterträda Johnson

The 2016 London mayoral election will be held on 5 May 2016 to elect the Mayor of London, on the same day as the London Assembly election. It will be the fifth election to the position of Mayor, which was created in 2000 after a referendum in London. The election will use a supplementary vote system. Mayor Boris Johnson has chosen not to run for re-election for a third term in office, having been elected as the Conservative Party Member of Parliament for Uxbridge and South Ruislip at the 2015 General Election, making this the first time since the inaugural election that the incumbent is not running. The main contenders are expected to be the Conservative candidate, Zac Goldsmith, the MP for Richmond Park, and the Labour Party candidate Sadiq Khan, the MP for Tooting, both of whom were selected by their parties in September 2015. A total of 12 candidates are standing, the highest to date in a London mayoral election.

Alexander Boris de Pfeffel Johnson (born 19 June 1964) is a British politician, popular historian and journalist who has served as Mayor of London since 2008 and as Member of Parliament (MP) for Uxbridge and South Ruislip since 2015. Johnson previously served as the MP for Henley from 2001 until 2008. A member of the Conservative Party, Johnson considers himself a One Nation Conservative and has been described as a libertarian due to his association with both economically liberal and culturally liberal policies. Born in New York City to upper class English parents, Johnson was educated at the European School of Brussels, Ashdown House School, and Eton College. He read Classics at Balliol College, Oxford, where he was a member of the Bullingdon Club and was elected President of the Oxford Union in 1986. Beginning his career in journalism at The Times, 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 became assistant editor from 1994 to 1999 before taking the editorship of The Spectator from 1999 to 2005. Joining the Conservatives, he was elected to the House of Commons as MP for Henley in 2001. Making regular television appearances as well as continuing with his journalism and book writing, Johnson became one of the most conspicuous politicians in the country. Under the Conservative leaders Michael Howard and David Cameron, Johnson served on the opposition front bench, first as Shadow Minister for Culture, Communications and Creative Industries and then for Higher Education. Selected as Conservative candidate for the London mayoral election of 2008, Johnson defeated Labour incumbent Ken Livingstone and resigned his seat in parliament. During his first term as Mayor, he banned alcohol consumption on those parts of public transport run by Transport for London (alcohol is sold and can be legally consumed on national trains to or from London termini), introduced the New Routemaster buses and "Boris Bikes", and championed London's financial sector. In 2012, he was re-elected as Mayor, again defeating Livingstone; during his second term he oversaw the 2012 London Olympic Games. In 2015 he was elected as MP for Uxbridge and South Ruislip, stating that he will not seek re-election as London mayor in 2016. Johnson is a controversial figure in British politics and journalism. Supporters have praised him as an entertaining, humorous, and popular figure with appeal beyond traditional Conservative voters. Critics have accused him of laziness and dishonesty, using racist and homophobic language, and elitism. The author of various books, he is also the subject of several biographies and a number of fictionalised portrayals.
