I thank the Cabinet Secretary for that response. As she has explained, this drug tariff is an England-and-Wales tariff, but, from my understanding, it is set according to the average sales from pharmaceutical companies representing the sector. But, none of these companies are based in Wales; they're large companies in England. So, it doesn't reflect usage or sales in Wales, and the result of that is that pharmacies in Wales are losing out. What discussions have you had, therefore, with the UK authority in order to have a tariff that reflects Wales, or even to devolve this to Wales?
