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.

So the Association has now been in touch with Mr Gove's office to find out what he means, because it is stumped.

The Association also points out there was an industry chat with a business minister on Tuesday, who made no attempt to find out if there was a supply problem for the vital ingredients of Covid-19 testing kits.

So this question of why there aren't enough tests for the virus is an even bigger mystery.

Also, 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.

Hmmm!. Tough one. NOT!
