But, having thought about it a bit, I'm not so sure. Brown's terrifying video earlier seems like a concerted attempt to wipe the slate clean; to shamelessly hide Labour misdemeanours behind that unnerving smile. And an apology from Darling tomorrow could be the second stage in that process. Not only would it be the change in tone that many Labour insiders have been calling for over the past few months, but - crucially - it could also capture some headlines, and deflect attention away from the grim public finances. Sure, voters are unlikely to forgive and forget. But an increasingly desperate Government might think it's worth a shot, so watch this space.
