London Mayor Boris Johnson arrives at Birmingham New Street Station before attending the Conservative Party conference
Boris Johnson has been given a thunderous reception by activists at Tory conference - but insisted he was completely loyal to David Cameron.
The London Mayor received a standing ovation after he delivered a gag-laden speech to more than 1,000 members at a fringe event.
He was heralded on to the stage in Birmingham with a video describing his re-election in the capital this year as "Mission Imborisable".
But while he boasted of achievements such as cutting crime in London, Mr Johnson played down speculation that he wants to take the Prime Minister's job.
"It is sometimes inevitable that the mayor of a great city will find himself saying things that do seem at variance with national policies," he said.
"Of course I am going to continue to lobby for a long term solution to our aviation capacity problem.
"No-one as a result should have any cause to doubt my admiration for David Cameron."
He stressed he was one of the first "Cameroons" in the 2005 Tory leadership contest.
"I believe that in tough circumstances he, George Osborne, are doing exactly what is needed for this country and to clear up the mess that Labour left."
The ConservativeHome.com event was given the tagline "Re-elected and Olympotastic".
