The next Liberal Democrat election manifesto will clearly show the commitments the party would "die in a ditch" to protect in any future coalition negotiations, Nick Clegg will say today.
The Deputy Prime Minister will paint the document as a starting point for talks with political rivals when he addresses the party's annual local government conference in Manchester.

He will tell them that next time there will be a clear distinction between "commitments" and "ambitions".
