Liam Fox 'pursued' over role of friend Adam Werritty

Liam Fox has said he will "carry on doing the job I'm meant to do", as the row about the role of his friend and self-styled adviser, Adam Werritty, continues.

Dr Fox faced more questions from journalists on a trip to Paris on Wednesday. A press conference in the city was cancelled for "logistical reasons".

David Cameron was also asked about his Defence Secretary's future at Prime Minister's Questions.
