Boris Johnson (born New York, 1964) is the current Mayor of London, as well as former British Conservative Party MP for Henley on Thames and a former editor of the conservative political weekly The Spectator. In 2008 he was elected to the post of Mayor of London, defeating the incumbent mayor, Ken Livingstone.
Boris Johnson's campaign for Mayor of London was based upon opposition to the style and policies that Ken Livingstone had introduced in recent years. Johnson promised during the campaign that he would roll back a recent expansion of Central London congestion charging Livingstone had introduced.. He also advocated the removal of articulated, or "bendy", buses that had been introduced to London. He also called for minor changes to law and order in London in the form of a ban on drinking alcohol on public transport (the London Underground in particular)  and the revocation of free travel for youths who misbehave on buses and trains.
Boris Johnson announced during the 2008 US presidential campaign that he favoured an Obama victory. Despite Johnson's birth in the US, he claims that he no longer has US citizenship because he chose to renounce it following trouble entering the US on his British passport that listed the US as his birthplace. However, he did not clarify whether he had ever formally renounced his US citizenship before a US consular officer and it is uncertain whether he remains a citizen under US law.
