Calamity may lead to concessions for Clegg

If the expected happens today, the political debate will rapidly move to whether Cameron should offer some concessions to Clegg to bolster his position. I hear there are two camps in Downing Street on this question with Steve Hilton a particularly ardent advocate of the no more concessions line.
 
Hilton’s position may surprise some but makes sense when you consider how his public service reform programme has, as Ben Brogan writes today, already been diluted for political reasons. 
 
My current expectation is that there won’t be many concessions to Clegg. One well placed Tory told me last night that “Clegg picked the question and the date. He can have no complaints.” But as Patrick Wintour writes in today’s Guardian, we can expect some of Clegg’s closest allies to take to the airwaves to ‘cathartically vent their fury at the way David Cameron let the No campaign assault Clegg’s political credibility.
