Diolch, Dirprwy Lywydd. Minister, in terms of COVID, you say that you've followed scientific advice continuously. I wouldn't agree with that, actually, but you say that you've relied on science. So, there's a proposal to dump 780,000 tonnes of mud from outside Hinkley Point nuclear power station into the waters just outside Cardiff, 1 mile off the coast. Now, scientists tell us that they're convinced—and they've said it on the record—they are convinced that the mud contains plutonium. So, in terms of you being the health Minister and also the AM for southern Cardiff, will you support the scientists' call to test the mud for plutonium, because it has never been tested for that? Diolch.
