Scotland Bill

I apologise to the Committee that I was not present through the earlier parts of the discussion of Clause 29, but my noble friend is making one of the most critical and crucial points in relation to these tax-raising powers. I would be interested if, when the noble Lord, Lord Sassoon, replies to him, he could put some figures on to the costs of implementation. He will know well that one of the essential ingredients of analysing the effectiveness of any taxation is the cost of collection. In this case, it is not just the cost of collection that we need to know about; it is also the cost of disaggregation of HM Revenue and Customs and the cost to the overall UK taxpayer, not just the Scottish taxpayer. If the noble Lord does not have those figures available at the moment, I would be grateful if he could give them to us in due course.
