The hon. Lady raises an interesting point about the static and behavioural effects. She will be aware that the shadow Chief Secretary to the Treasury said:
“We have a choice about a tax rate that would raise £3 billion”.—[Official Report, 5 November 2014; Vol. 587, c. 849.]
Does she believe that putting the 45p rate back to 50p would raise £3 billion for the Exchequer?
