I do not have the faintest idea. If the hon. Gentleman wishes to write to me, I will try to give him a better answer. Yes, my point is anecdotal, in that the Government have a figure for certain forms of accident and emergency doctor provision in the whole of the UK, and there is no shortage across the whole country, just in certain areas. That is why we may need some tweaking to ensure that we are able to maintain the services on which we all rely. There are similar issues in relation to nursing, not least because one of the elements of migration that we must bear in mind is that many British nurses—although no statistics have been provided since 2008—are choosing to work in countries such as Canada, New Zealand and Australia. It is therefore difficult for us to plan precisely.
