David Cameron added to the shambles over EU policy today when he ordered Lib Dem Cabinet ministers to stay away from a Tories-only faction meeting.
The Tories will shut out their junior partners this morning when the PM holds a special gathering of Tory Cabinet ministers in a bid to stop a bout of public squabbling in his own party.
Mr Cameron will attempt to explain to fractious Tory ministers what he intends to say on Friday in his much-delayed speech on the EU, originally slated for December last year.
His Lib Dem deputy Nick Clegg irritated many Tories today by warning in a radio interview that "uncertainty" over the EU would have "a chilling effect on jobs and growth."
Asked if Mr Cameron will speak on Friday for the Con-Dem coalition or simply as a Tory, a Downing Street spokesman retorted: "The Prime Minister is always the Prime Minister. So when he speaks he will be the Prime Minister."
