Could Brown be about to jump?

The Prime Minister has arrived back in London and is speaking individually to cabinet ministers. This sounds like he maybe about to make his intention to resign as leader of the Labour party.

It sounds like phone calls with Nick Clegg have not gone well. They may be discussing a handover to someone else as a caretaker in the hope that it may encourage the Lib Dems to make a deal. That would be my hunch.

Squiffy.
