going to expect you to be an authority on the ideology and philosophy of taliban leadership, but let's start with the practical question. this community who has arrived in the uk and many other countries around the world, many of those people are highly qualified professionals, and in the case of the british nhs, they are doctors and nurses and others. are there many practical hurdles that would stop people with those kinds of qualifications actually practising here, and indeed in other western countries? i am glad you asked me that, sean, and not further developments on afghanistan because i would defer to our colleagues on that. i think i may ask and it would be hugely valuable to the nhs, which for decades really, almost since it was founded, has needed doctors, nurses and other staff from other parts of the world, and they have greatly enriched the nhs and provided great service and skills. the general medical council, the main regulator, has to look at the qualifications and verify that they are suitable and that the qualifications match up what's required in the uk.
