Scotland Bill

Can I take my noble friend back to the debate we had earlier when the noble Lord, Lord Turnbull, argued that it was important to have in the Bill specific provisions relating to borrowing powers? I think that my noble friend indicated that more primary legislation would be required; he used the phrase “primary legislation”. Can we take it that these powers would not be used, for example, to put in place a borrowing regime for the Scottish Parliament, taking into account what he has just said now with what he said earlier this evening?
