—you can mitigate the risk, as well. I have limited time, I'm afraid.

You can mitigate the risk, as well, because the block grant adjustment approach allows for those kinds of risks to be mitigated. We mitigate currently through the fiscal agreement already in place in terms of the budgetary risks that arise from the different distribution of taxpayers that we have in Wales, and that block grant adjustment mitigation policy could be adjusted further to provide mitigation in the way that the Northern Ireland Fiscal Commission has suggested if income tax bands are also devolved there.

So, there are things that we can do to mitigate the risks, but there are great opportunities here, based on the Scottish experience, not only to generate additional revenue, but also to create a far more progressive tax structure than we're currently given by Westminster.
