Scotland Bill

This feels like Groundhog Day. I thought that the committee of the Scottish Parliament that looked at the latest Bill just before Christmas last year had wanted to include air passenger duty in it, but I am told that that is not the case and that the committee was prepared to wait. It is certainly not prepared to wait on the aggregates levy. As noble Lords will see, it takes three pages of legislation to provide for the power to obtain the revenue from the aggregates levy. Here, once again, we have a case of St Augustine: ““We are in favour of this, but we don't actually want to do it now””. The argument being put against including this in the Bill is that it would be subject to legal challenge—the power might be put in the Bill but the result might be that no revenue for the Scottish Parliament arises from it. That is not an argument for not putting it in the Bill. Primary legislation is difficult to achieve, and it is even more difficult to achieve in a decent time in Westminster. I think that my noble friend should accept my amendment—which is probably technically deficient—and extend the range of tax powers available to the Scottish Parliament, if for no other reason than to mitigate the effects which we have talked about at length today of having a narrower income tax base. I beg to move.
