I am grateful to my hon. Friend for that powerful point. As I said, I will explore the details in relation to data and the argument over the yield from the 50p rate, but he is right: we cannot continue to rely on a report produced when the rate had been in place for only one year. The Government should accept the new clause and produce a much more comprehensive analysis.
It was the Labour Government who introduced the 50p rate, which came into effect in 2010-11, a decision made after the financial crisis, as we sought to get the deficit down. When this Government came to power they did not say anything in the coalition agreement about abolishing the 50p rate, but in 2011 the Chancellor said that he would ask HMRC to look at the yields from the 50p rate, which was the warning signal that he was looking to cut it. In 2012, with HMRC’s report “The Exchequer effect of the 50 per cent additional rate of income tax” to back him up, the Chancellor cut the rate to 45p.
Why go through the process of looking at yield and getting HMRC to produce a report? Everyone knew that there were not enough data to come to an accurate view about yield because the rate had not been in place for long enough—a point about which I shall say more later. Well, the Chancellor knew that he needed cover for that deeply ideological decision so he was desperate to claim that a 50p rate raised very little money. If he could stand before the House and say that it raised hardly any money at all, never mind the uncertainty and the incompleteness of the data, he calculated that he could justify giving a tax cut to the richest in our country, knowing that on his watch ordinary people—those on middle and lower incomes—would pay the price for his economic plan, which has failed on the terms that he set for himself when he came to power in 2010.
