In order to assess the real implications of a land value tax, we need more data, of course. That's become clear in some of the work undertaken by the Bangor University report. The first recommendation in that report was to go about gathering the necessary data in a more meaningful way, perhaps. So, can I ask you what work the Government has done or intends to do to gather that data in order to lay the foundations for the discussion that we need to have on a land value tax?

Thinking that there's been no revaluation for 20 years does tell us a lot about where we are and how outdated the situation is. So, would you agree with me that we need to move to a more dynamic footing, where revaluation happens more regularly, whilst of course being aware of the need to create mechanisms that even out the peaks and troughs that would emerge as a result of doing that?

And finally, you refer to new techniques or technologies in your statement. What sort of things do you have in mind in that context? Thank you.
