What will Gordon Brown do if the bank bail-out doesn't work? One answer being put forward in Blairite circles yesterday is that the Prime Minister will dump his ultra-loyal Chancellor Alistair Darling - and bring in Vince Cable as a part of a deal with the Liberal Democrats. It may sound extraordinary, but the Mole heard it more than once yesterday.
The Lib Dem Treasury spokesman's stock at Westminster is sky-high. Like some biblical prophet, Cable has long been warning of the financial crisis that has now engulfed the British economy. He was, for instance, one of the first to come up with the idea of nationalising Northern Rock.
Would Brown do it? Those advancing the idea reckon that his current mantra that he will do "whatever it takes" is a political as well as an economic statement.
