LibDems and civil servants are openly discussing when, not if, Huhne will be going. There is some logic to getting the mess out of the way before the weekend, and the country will be able to cope without a Climate Change Secretary for a couple of days. The two yellows in the lead to replace him in the Cabinet role seem to be Ed Davey, who has been invisible as a Business Minister, and Foreign Office Minister Jeremy Browne, who has been all over the TV whenever Hague is busy being briefed by MI6.
Both are Orange Bookers, though Browne is seen as more right-wing which will likely dent his chances for the soppy climate change brief. Obviously Laws is toxic and Guido understands that Sarah Teather has little chance of a promotion.
