Should he stay or should he go?

Pressure was continuing to mount on George Osborne last night as further details of the ICM Guardian Poll came out.

It shows that not only has his satisfaction rating plummeted to below that of Deputy PM Nick Clegg but also that over half of people aged over 35 and therefore more likely to vote want the Chancellor replaced.

Osborne's overall satisfaction rating is -32, Clegg is -26, Cameron -12 and Ed Miliband -13.

Experts however say that Cameron is unlikely to move Osborne by pointing out that the last time a Chancellor was removed by a Prime Minister in mid-term was when Norman Lamont was replaced by Kenneth Clarke following Black Wednesday in 1992.
