Finance (No. 2) Bill

Given that before and after the Budget the corporation tax rate in France was 33%, while in Germany it was 29% and in Britain it was 21%, why is it necessary to reduce it to 20% and in so doing to get rid of 5% of the corporation tax yield? How long will it take to get that 5% back? Will we produce 5% more inwardly-investing businesses or will the size of the business community grow by 5% to make it up? We are already extremely competitive on that front, so how long will it take to make up that money, which the Minister has given away for no apparent reason?
