Thank you, Simon, for that question. Just to say, the success that the authority is having at present comes from the hard, preparatory work that was done over the past years, including the work of the committee, which has been part of preparing the authority for the work that they are now undertaking. As regards the new taxes, we are continuing to work with the United Kingdom Government on more than one aspect. We are talking to them about what they are doing in the field of a plastics tax, and we’ve agreed to take the lead on this debate in Wales and to feed into the call for evidence— I've forgotten the Welsh word for 'evidence'. 'Tystiolaeth', of course—that the Treasury issued in March.

We also want to start to talk about Gerry Holtham’s work with them and what he has suggested in the care sector, but I have written—and I have shared the letter with the Finance Committee—officially to the Treasury to initiate the process in the field of vacant land. This is the one that we wish to use to test the new system that we have in the 2014 Act. I have written to the Treasury and we are preparing on an official level the work that we need to do with them. I’m looking forward to receiving a positive response from them and to begin this work in the Assembly—the more detailed work on the policy—and to see whether it will be possible to bring forward a Bill to the floor of the Assembly in order to create the first Wales-only tax through the process available to us.
