Clegg needs more time than the markets are going to give him to make the least worst decision.
The Irish equivalent of Radio Four (RTE1) has an interesting take on this part of the process. Tonight, they were sagely saying that getting things sorted in 4-5 days would be very fast and that coalitions can take weeks to establish. They are clear too that Clegg's power extends to the exact moment when he makes his deal.
At the moment here we have a coalition in which the Greens participate. They had a Lib Dem-like pure reputation until a few years ago, but by entering into, and clinging to, a coalition with Fianna Fáil they have destroyed their own credibility. If they retain 3 seats in the next election it will be a miracle.
I think it would be very useful for the BBC to step back and give us a guided tour of how coalitions have played out elsewhere in the EU to better illustrate the tensions and possibilities.
