The Deputy Prime Minister's office has responded to Ed Miliband's call for cross party talks to block the planned pay rise for MPs.

Nick Clegg's aides also point out that the Independent Parliamentary Standards Authority does not publish its recommendations until Thursday, so it would be wrong for politicians to get involved in a process - which is rightly independent of politicians - before the announcement has been made.
