Finance (No. 3) Bill

That is absolutely right. I said when I intervened on the right hon. Member for Gordon that of course taxation needs to be sensitive to profitability, but that Ministers also need to understand that investment decisions are sensitive to tax and other costs. Although the field is mature, some of it is unexplored. If the perception is that it is expensive and that there is tax instability—which has been said—we will lose the ability not only to continue work in some of the mature fields, but to explore as yet untapped reserves, albeit in a mature sector. As I have said, this is the most damaging measure in the Budget for economic growth. Although I respect the attempts to amend it and the tabling of amendments for the Government to discuss, we think that it is so damaging that we hope Mr Hoyle will be able to call on hon. Members from across the Committee to resist clause 7 very vigorously indeed.
