Thank you very much and this is something that we've explored in the Chamber before the introduction of the Welsh rates of income tax, so it's good to come back to it again. Welsh Government and HMRC undertook a large amount of work to ensure that we could identify everyone who is eligible to pay their taxes in Wales. We have no reason to suggest that we feel that there is an issue with that piece of work in terms of identifying those individuals who should be paying Welsh rates of income tax.
