We know about the problems that exist, which Scotland had when it first had income tax devolved, and if this is the only problem that we have, then I think it should be solved fairly quickly. But when you see a problem occurring like this, there's a nervousness as to whether other problems might have occurred as well. 

We know the bigger problems in Scotland were the failure to allocate Scottish taxpayers to Scotland and to accurately predict the income tax income and receipts that were going to come into Scotland. Is the Minister confident that everyone who should be a Welsh taxpayer, apart from those who have just been identified, are paying the correct Welsh rate of income tax, especially those who do live in Wales, but work in England?
