Next Prime Minister odds: Who will replace David Cameron?

Boris Johnson is the odds on favourite to be the next prime minister after David Cameron announced he is to step down.

• Boris Johnson

The bookies' favourite, the former mayor of London is a 52-year-old journalist turned politician. More celebrity than politician, he is seen as one of the more charismatic figures in Westminster. He re-entered Parliament last year after eight years as mayor and led the Leave campaign.

• Theresa May

The longest-serving home secretary in history, who turns 60 later this year, has long been mentioned as a potential future leader of the party.

She famously once described the Conservatives as the 'nasty party'. She is seen as one of the toughest and most competent operators in Whitehall.

• Michael Gove

The 48-year-old has long played down his chance of being prime minister. The former Times journalist is a close friend of David Cameron and George Osborne. He was a combative education secretary and is currently justice secretary. Has been a prominant Vote Leave campaigner.

• Andrea Leadsom

Andrea Leadsom has been seen as a star performer for the Vote Leave campaign, appearing in high-profile debates.

She was part of the 2010 intake and was made economic secretary to the Treasury in 2014.

She could be a contender for chancellor, if not leader.

• Priti Patel

The employment minister has long been tipped as a contender for the leadership. The 44-year-old Essex MP is the daughter of Ugandan immigrants who ran a successful chain of newsagents. A very high-profile figure in the campaign to leave the European Union.

• Ruth Davidson

The Scottish Conservative leader has impressed with her performance during the campaign and electoral success north of the border last month. But a Westminster seat would need to be found for her to have a viable shot at the top job. Ms Davidson has also suggested such a move is not for her.

Chancellor George Osborne is an outsider at 33/1.
