US Edition Boris Johnson's Commons comeback moved a significant step closer as he was selected to fight a safe Tory seat at next year's general election.
The London mayor saw off the challenge of three rivals to secure the support of party members in Uxbridge and South Ruislip as their pick for 2015.
Speaking after his selection, he said he was "obviously thrilled" and said he was sure the Conservatives would win an absolute majority in 2015.
Before the ballot, Mr Johnson and his three rivals made a behind-closed doors pitch to party members in a school hall.
The mayor's bid survived concerns over his determination to see out his full City Hall term, which runs to 2016, at the same time as being a local MP.
Mr Johnson won outright on the first count, without the need for a second round.
The colourful politician's decision to return to Westminster has stoked speculation over his hopes to succeed David Cameron as Conservative leader.
The Prime Minister insists, however, that he would be delighted to have the mayor back in Parliament, saying he wants his "star players on the pitch".
Mr Jonhson added: "I am obviously thrilled," he said after winning the contest outright in the first round of voting following behind-closed-doors presentations to the local association in a school hall.
He sought to play down suggestions it marked the latest stage of a mission to succeed David Cameron as Tory leader.
"No, this is the first stage in the campaign to retain the seat of Uxbridge and South Ruislip for the Conservatives and to get across the message of what the Conservatives have achieved not just in London but across the country as a whole in turning the economy around," he said as he emerged.
"And urging people not to throw it all away by allowing Ed Miliband and the Labour Party to get in.
"It will be a tough fight, it will be a long fight. But I have no doubt whatever that we are going to be able to return David Cameron and the Conservatives with an absolute majority in 2015.
"This is Act One, Scene One of a very long process and what I have got to do now is have a lot of talks with people here in Uxbridge and South Ruislip, get to know people, get to know the association better. There's a lot of digging in to be done."
Mr Johnson insisted it was not a problem to be an MP and continue running London until 2016.
"It has been done before and I see no reason why it shouldn't be done again," he said.
"I would point out that it is possible to be both an MP and have a very big job such as foreign secretary or prime minister at the same time."
He admitted that he had no immediate plans to relocate to the constituency.
"I live in London. I have got a home in London. I don't rule it out but it won't happen immediately," he said.
Praising the quality of his opponents, he said: "It was a very enjoyable selection process and I want also to pay tribute to the other three candidates who were here tonight who were all very good indeed and I am sure they will go on to get good seats."
The others in the frame were the deputy leader of the local council David Simmonds, another senior councillor Simon Dudley, the deputy leader of Windsor and Maidenhead council who was born in the constituency, and Harrow-born barrister Suella Fernandes.
Mr Johnson previously served as MP for Henley for seven years before leaving to take up the City Hall reins in 2008.
He will defend a majority of 11,216 in the north-west London constituency held by former deputy chief whip Sir John Randall, who is stepping down.
The others in the frame were the deputy leader of the local council David Simmonds, another senior councillor Simon Dudley, the deputy leader of Windsor and Maidenhead who was born in the constituency, and Harrow-born barrister Suella Fernandes.
He told the Telegraph how he is relishing the opportunity to re-connect with ordinary voters and have a "brilliant" time as a prospective MP.
Mr Johnson, who was last night expected to become the Tory candidate in Uxbridge, said he "loved" the contact he had with the public as an MP before becoming Mayor of London.
Winning the seat is widely regarded as a crucial stepping-stone for Mr Johnson his ambition to succeed David Cameron as Tory leader.
On Friday night he faced three other Tory candidates: Simon Dudley, the deputy leader of Windsor and Maidenhead council; Suella Fernandes, a barrister; and David Simmonds, the deputy leader of Hillingdon council.
Mr Simmonds, who until Mr Johnson threw his hat into the ring was the favourite, has said the contest against will be a “David and Goliath challenge”, but warned the Mayor that this “David has a good track record”.
Each candidate was asked by members of the local conservative association what qualities they would bring to the job.
Mr Johnson, who was the MP for Henley from 2001 to 2008, told the meeting that while he "loves" meeting constituents his opportunities have become more limited since he became Mayor of London.
Mr Johnson also appealed to the association as a "true Conservative", saying that he wants them to "go on a journey" with him to help support an outright Conservative majority in 2015.
He will also stress his work for the area as the Mayor over the past seven years has made him well-positioned to represent the area.
All four candidates oppose further expansion of Heathrow airport, which provides thousands of local jobs but also subjects residents to noise pollution.
Mr Johnson has previously called for the airport to be replaced with housing, but in recent weeks said he would be prepared to see it remain open provided a new Thames Estuary hub took on the lion’s share of the UK’s air traffic.
He told party members that he would continue to fight against a third runway if he was their MP.
