Building on the tax powers that you have, finance Minister, are you in a position this afternoon to inform us, for every penny that you might seek to raise, if that was your advice to Cabinet at the budget-setting period, how much extra money would come into the Welsh Government coffers in the 45p and 40p threshold, and, conversely, every penny you might take off, what that would lose to the Treasury here in Wales? And, any behavioural concepts that you might have modelled into your advice to Cabinet, would you make that available so that Members are in possession of the full facts when considering the tax powers?
