Diolch, Llywydd. Can I just say that I've spied my former colleague on the Finance Committee, Peter Black, up in the gallery? It took me back to the last Assembly election, when we were looking forward to tax devolution as a distant, although approaching, inevitability. We are now the other side of that devolution.

You said, in answer to Mark Reckless earlier, in relation to land transaction tax, which I want to question you about as well, that we are now in the period of collecting evidence about the introduction of the taxes, and the effect of those taxes, rather than mere speculation. If, as you said in answer to Mark Reckless, there does, at some point, appear to be an issue with the rates of land transaction tax, at what point will you act to make sure that those rates are reduced so that they're more comparable with those across the border?
