My hon. Friend is, of course, quite right. That is yet another example of the Governments economic and tax policy unwinding disastrously over the past two years with the former Chancellor, now as Prime Minister, continuing patterns of disastrous stewardship of the finances.
My other question is about what behavioural changes there will be. What behavioural changes does the Minister predict will happen on the overall tax take from those changes? At the moment, they seem to be predicated entirely on no behavioural change, which was the point made by the hon. Member for South Derbyshire in his intervention. How does the Minister feel about jeopardising our long-treasured, progressive system of taxation, where bands go up the more that one earns, and introducing this rollercoaster? What impact will that have on the message that the Government are sending out to the people of this country?
