I'm grateful to you for that, Minister, and I think the whole Chamber will look forward to that update. As I've said, it's a situation that we're all hoping will be avoided, but does seem to be becoming more of a real threat. I'd like to give you a specific example to illustrate the dangers that we face, which I'm sure you're very well aware of. The radioactive isotope technetium is used in about 850,000 scans in the UK for a whole range of conditions, including heart disease and cancers. This product has a half-life of just 66 hours, meaning that it can't be stored and stockpiled. Currently, the UK as a whole relies on a continuous supply of this product from France, Belgium and the Netherlands, and that supply is governed by the Euratom agreement. The nearest potential non-EU suppliers are in South Africa and Ontario in Canada, and obviously couldn't be useful to us in this situation. And, obviously, this is only one example, because there are many types of isotopes that can't be stockpiled. We know that even under the existing arrangements Northern Ireland had problems twice—in 2009 and 2013—due to the logistical challenges of getting this product in time. Can you explain how hospitals in Wales will be getting these types of products in the event of a 'no deal' Brexit?
