Of course the big shadow hanging over the CSR tomorrow will be that of Gordon Brown. After all, he got us into this mess in the first place. Reading the final pages of Peter Mandelson's book it is clear that he was intent on a spend, spend, spend approach and resisted all attempts by Alistair Darling to rein him in.
But since the election he seems to have opted out of politics altogether. He's appeared in the Commons two or three times but that's about it. Will he be in the chamber tomorrow to hear about the consequences of his profligacy? I doubt whether he'll have the courage. He won't like to recall the fact that post 1997 John Major was an assiduous attender and would regularly sit there and listen to his record being trashed by the very same Gordon Brown that seems to believe that the deficit is really nothing to do with him, but can be blamed on the world bankers. If only it were that simple.
Brown should not only show up tomorrow. He should speak, and defend his appalling record.
But will he have the courage?
