I thank Mohammad Asghar for those suggestions, and I'm very happy to pursue them with HMRC to see whether they would be a practical way of continuing to explain to citizens in Wales the changes that fiscal devolution have brought about. He's right to point to the fact that there are some detailed discussions that have gone on and, indeed, detailed analysis that HMRC are undertaking of the 98 cross-border postcodes, where people could be living in England or in Wales, in order to ensure that notification letters are issued only to those taxpayers living in Wales. We think there are fewer than 900 people in that situation, but the additional detailed work that HMRC has carried out will mean that letters to those remaining citizens will be issued by 10 December.
