So it is two Tories, IDS and Osborne, who have provided the most spectacular row of the coalition so far. But it is worth noting that, as Tim said on Sunday, a truce has been reached between the two men and the contours of a deal agreed. It is also my understanding that both sides have put a stop to any briefing that could be considered as negative.
A deal on welfare reform looks more far more likely now than it did six weeks ago. If IDS and Osborne can come up with a package that both increases work incentives and plays its part in deficit reduction then they will have achieved something that will give this government definition.
