In accordance with my statement, the timetable for what we can do is in the hands of the UK Government, which must consider the proposition that I have put to it in advance of the budget. It can do that and respond by the time of its next budget speech at the latest, which will help to inform the Scottish budget.
Unless it can find a legal remedy or a fiscal remedy, the UK Government has a responsibility to address the issue. I know that it would be difficult ever to convince Patrick Harvie or the Greens of the policy, but the principle that we all agree on is the successful and competent delivery of devolution. In this defective state, the tax cannot be delivered in Scotland; that is for the UK Government to resolve in the fashion that I have described.
