I will come back to that in a moment.
It would require the tax system to be fully functioning and for there to be an agreed macroeconomic fiscal framework across the whole of the UK. That would require agreement between the Scottish Government and the UK Government—that is to say, there would be other people at the table who had to say yes to things—so it is not possible to put a hard and fast timetable on the powers. If, however, we can agree on full fiscal autonomy tonight, and the Scottish Government’s ability to draw down the powers at the right time, then with good will we can get agreement on the fiscal agreement and the overarching framework, and we can all get to work.
