Amendment of the law

The hon. Gentleman is always extremely interesting to listen to on financial matters. I, too, have been a strong opponent of ID cards and Trident—but does he acknowledge that cutting investment in those projects would also reduce the number of jobs available in the Scottish economy and elsewhere? Specifically, the increases in expenditure, which he is criticising in relation to the Chancellor's statement, will have a knock-on effect through the Barnett formula, which he adores and I detest.
