Re: Clearly states the first batch is manufactured in EU, not UK
Boris appears to have done the, "Guys, did you really think this through? Perhaps you'd like to explain to us your thinking before we respond?" thing, and the EU have gone, "Oh. Bugger. Yeah, that wasn't us, ignore the press reports, don't know who started that whole story, nothing to see here."
Might even be true - undoubtably some people in senior EU roles would like to create conflict so they may have jumped the gun before the wiser heads stepped in.
