Who will be the next Conservative Party leader and Prime Minister?
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.
