London Mayor Boris Johnson given rock star welcome by Conservatives
Johnson's arrival at Conservative conference attracts media scrum and hero worship from members, but he asserts loyalty to David Cameron

Britain's Conservative party gave maverick London Mayor Boris Johnson a rock star welcome at its annual conference. But while he left the prime minister, David Cameron, in the shade, it is still uncertain if he is a real threat.
Johnson, still riding high on the success of the London Olympics, was mobbed by supporters chanting "Boris! Boris" as he arrived by train on Monday in Birmingham, central England.
He later received two standing ovations at a fringe meeting.
And despite the mayor's claims that he is not interested in the premiership for now, it seemed more like a campaign rally for Cameron's job.
But while Cameron is struggling in the polls and the British economy is flatlining, activists and lawmakers still appear wary of believing the party's future really lies with the blond mop-topped Johnson.
"We came here to be entertained, as you are never sure what Boris is going to say," Conservative activist Sue Lissimore said as she joined a queue to see Johnson. "But I believe you need someone a little bit more sensible to be prime minister."
