I thank the noble Baroness for her question. This advice has come not from the Prime Minister, but from the Royal College of Radiologists. On the basis of that advice, we know that many services will be unaffected. For other services, the NHS is already working closely with suppliers to minimise the impact of changes to medical radioisotope delivery times, which are expected to be a matter of hours and easily managed by clinics. But it is appropriate that they should be given sensible and practical advice to ensure that patients are protected and that patient safety is maintained to the highest possible standards.
