Nick Robinson tonight on the Ten O’Clock News will say that “the BBC understands that..” David Cameron intends to give a Statement of Principles tomorrow. This may be spun as the “almost Clause 4 moment”. The Conservative party membership will be called upon to vote on it. This will face down right-wing critics with a “the membership backs change” definitive verdict. The old right headbangers will be buried.

Sorry to spoil the scoop Nick.
