First Minister, whilst Mark Isherwood and I might not see eye to eye on many political issues, we have worked closely together on the question of medicinal cannabis with the MS Society. So, I wonder whether I can ask whether an assessment has been undertaken of how many children in Wales have severe epilepsy but could also benefit from the availability of cannabis oil like Billy Caldwell. And will you also see that preparations are made to ensure that the NHS in Wales is prepared to meet the demand for medicinal cannabis and prepared to prescribe it to patients if and when restrictions are relaxed by the UK Government?
