From Robert Paxton of ITS news 2 days ago.

"Well I've just talked to the Chemical Industries Association, which represents the UK's very substantial chemicals industry.
It has contacted its members, and they've said there is no shortage of the relevant reagents.
. . .
if it turns out there is a shortage, these manufacturers are more than happy to increase their production.
But they need to be asked, which has not happened.
We have 2 stories and as I said earlier we make a choice of who to believe. Someone who knows what is happening in the industry or a politician trying to cover his own arse."

It seems the unnamed source is uncertain whether there is a shortage. He categorically states there's no shortage, and then says that if there is a shortage they can do something about it.
