Boris Johnson has used his platform speech to the Conservative Party Conference to insist he is completely loyal to David Cameron, hailing the "fantastic job" he is doing as Prime Minister.
Boris made a point of singling Mr Cameron out for praise, in response to speculation that he was positioning himself as a future leader of the Conservatives.
He commended the Prime Minister for his "firm leadership" and his ability to make "tough decisions", before predicting that he would lead the Tories to victory in a general election scheduled for 2015.
Earlier this morning, David Cameron denied that he was envious of Boris Johnson's "rock star status", after the Mayor was mobbed on arrival at the conference in Birmingham.
The Prime Minister told ITV1's Daybreak that he was resigned to the fact that other people might be more popular than him.
