The Member will be aware of the letter published by Simon Stevens, the chief executive of NHS England on this matter, sent to the House of Commons's Health and Social Care Select Committee. That set out that Northern Ireland and Wales have stood alongside England in the negotiation of the agreement that has been reached. My expectation is that those terms will be honoured. I made public comment yesterday that I would sign up today to exactly the same pro-rata terms for Wales, and I wish to be able to do so. That is my commitment. There should not be a delay for any family in Wales. I look forward to a properly constructive and honest response from Vertex that allows that to take place.
