I don't really know with Brown anymore. Sometimes his policy statements sound vaguely sensible, but I'm not so easily charmed by talk alone.
I cynically expect this to just be an attempt to diffuse Clegg. At the leaders debate Clegg put forward the populist notion of putting an extra tax
on the banks, I assume in part to claw back some of the money tax payers lost in the bailout, but also because their profits are so vast it's
unclean.
Attacking the banking system right now would be a wise move for any politician, but do we really trust any of them to be serious about it once
elected?
