Finance Bill

I apologise to the hon. Gentleman in advance for going back to what was said during the general election, but it is important in this context. The Liberal Democrats said that they were in favour of a banking levy, as he has just said, but they went further and said that it would be in addition to corporation tax. What we are debating is corporation tax that compensates the banks for the levy, cancelling it out. How can he possibly defend that position?
