This is what Ed Balls said today about the revenues from the 50p tax rate:

"The latest figures show that those earning over £150,000 paid almost £10 billion more in tax in the three years when the 50p top rate of tax was in place than when the government conducted its assessment of the tax back in 2012."

If there is disagreement over this claim (and there is) let's see the rationale from those who question it. And if Ed Balls needs to defend his claim - which I think he does - let's see that defence, in detail, as well.
