Diolch, Llywydd. Cabinet Secretary, yesterday, in your statement on the vacant land tax, I described you as a jack of all trades when it came to developing new taxes; you've got a lot of different taxes on the go at the moment. In yesterday's statement, you spoke about testing the machinery in terms of the vacant land tax. If I can widen that question out into other potential new taxes that the Welsh Government might be considering in future, clearly one of those potential taxes would be one to deal with the social care time-bomb problem, and a potential social care levy, as other Members have discussed in this Chamber. Could you tell us: have you given any thought, as of yet, to a potential social care levy, and have you had any discussions with your colleagues about that?
