On the tight-rope issue that is the EU treaty, the Tories are campaigning hard for a referendum, which Gordon will not concede. What Cameron has refused so far to concede to his own right-wing is a retrospective referendum should they be in power in 2010 – two years after the treaty will have been confirmed by Parliament.

Hague has been firmly evasive on this point, Tory EU-headbangers have also been, well, as headbanging as always on the same point. Tomorrow’s new “CANCELLED” poster from the Tories has now muddied the waters. As soon as it appeared on ConservativeHome, UKIP supporting Chad Noble spotted that the poster implies “A vote on the European Constitution” is “now delayed until the election of a Conservative government”.The Lobby are lined up to hear a speech from Cameron tomorrow on his “vision”, what is the betting that they will be asking him about this commitment? It is an issue the Brownies have deliberately been trying to stoke up in the press to cause trouble and division with the Tory ranks. Somebody at CCHQ is going to get a bollocking tomorrow…

UPDATE : The Devil has taken a more detailed look at the Tory (non)commitments overnight. Are they meaningful? He thinks not.
