The London mayor Boris Johnson was given a thunderous reception before his speech on the sidelines of the Tory conference in Birmingham this evening.
His gag-laden speech made reference to Cameron-supporters as "Cameroons" and his own re-election as "Mission Imborisable".
But he also confirmed his loyalty to the Prime Minister and made a effort to dispel rumours of a clash over the third runway at Heathrow:
"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.
"No-one as a result should have any cause to doubt my admiration for David Cameron."
Boris has pledged his loyalty to the Prime Minister, telling the Conservative Party conference David Cameron will win the 2015 election.
London Mayor Boris Johnson will deliver a keynote speech at the Tory party conference, amid speculation about his leadership ambitions.
