David Blunkett has said nothing is "off limits" in the pensions debate, putting him on a potential collision course with the chancellor.

The new work and pensions secretary said he would consider all options to close Britain's savings black hole when the landmark Turner report is published later this year.

Blunkett said "we need to be able to address quickly, decisively where we are going".

However Gordon Brown and his advisers have said changes such as compulsory savings would require a cross-party consensus and support from the electorate.
