Diolch yn fawr iawn, Llywydd. I hope that the First Minister will feel that he owes the Assembly a duty of candour on this issue, but clearly we're going to get no further on it today and we'll have to wait for the debate next week to see whether we can make progress, so I would like to turn to another issue.

The First Minister said recently that he would like to see air passenger duty devolved to Wales so that he could abolish it for long-haul flights, and I welcome the First Minister to the ranks of tax cutters and tax abolishers in the Assembly. It makes a change from all the other taxes that he wants to introduce. But this is, of course, in a way a form of tax avoidance that he's in favour of, because it will give Welsh airports a small but significant advantage over airports on the other side of the border in England that will still have air passenger duty applying to them. So, can the First Minister explain to me how it is that he can reconcile his views on air passenger duty with his other views that the tax system should not be used for tax competition within the United Kingdom or, indeed, with other countries?
