With the Prime Minister asking for the preliminary findings of an inquiry into Liam Fox's working relationship with Adam Werritty to be on his desk tomorrow morning, the position of the defence secretary looks precarious. This morning, the Observer [2] produces video footage of Fox's meeting with the president of Sri Lanka last year at which Werritty was present, and which appears to contradict the defence secretary's earlier insistence that his friend and former flatmate had never attended any meetings with representatives of foreign governments.

The press pack has the scent of its quarry in its nostrils. Here's what the papers are saying about Mr Fox today.
