Yes, I wouldn't be averse to a no-detriment principle there, so you can infer that, but I think that that would have to be very carefully considered, and I think that, over the medium term at least, if that was done, there should be mechanisms within the Welsh Government so that tax rates are seen to be competitive.

I know that we've often had these discussions, Mike, about volatile taxes like land transaction tax—of course, all tax is volatile, to a certain extent—and what would happen if there was a major shock to the economy. Borrowing, of course, could be used to cover any shortfall in the short term. But, I think, yes, no detriment over the longer term should be the aim.

In conclusion, Deputy Presiding Officer, and returning to the first part of the motion, the Welsh Conservatives believe that Wales's membership of the United Kingdom has been beneficial to the Welsh economy over many years. If you just look at Wales's estimated fiscal deficit alone in 2017-18, estimated at around £13.7 billion, that is currently supported, of course, largely by the UK Government. That wouldn't happen if Wales was independent.
