PRIME Minister David Cameron today defended Defence Secretary Liam Fox, who is at the centre of a storm of allegations relating to his links with close friend Adam Werritty.

Mr Cameron, who spoke to the minister by phone yesterday, said Dr Fox had given a good account of himself.

Later today, the Prime Minister will receive the interim findings of an internal inquiry into the allegations by the top civil servant at the Ministry of Defence.

His official spokesman this morning told reporters that Mr Cameron will discuss the findings with Cabinet Secretary Sir Gus ODonnell, but it is not yet known whether he will order a formal inquiry into possible breaches of the ministerial code of conduct.

Asked if Mr Cameron had full confidence in Dr Fox, the spokesman told a regular daily media briefing in Westminster: "Absolutely."

Speaking at Heathrow Airport this morning, Mr Cameron said: "Liam Fox does an excellent job as Secretary of State for Defence. He gives that department good leadership - I think we've seen that with all that its had to deal with in the Libyan campaign.

"Of course there are a whole series of questions that have come out of the media that Liam is answering; he answered them last night, he gave a good account of himself, he's in front of the House of Commons today.

"And I'll be getting the interim report from his permanent secretary at the Ministry of Defence, so I hope well be able to deal with it in that way."
