Scotland Bill

There is a point that my noble friend is not addressing: no amendment has ever been brought forward to devolve allowances. It would be a major change to make at this stage of the Bill and he has not advanced the idea before but, that apart, it did not commend itself to the Calman commission or to the Government. Is he saying that the United Kingdom Government cannot make changes to a tax allowance which will benefit all taxpayers in the United Kingdom and that, if they do, they will be giving with one hand and the Scottish Parliament will be taking away with the other? That is an untenable position for a unionist to take.
