Iranians were the first to publish about the synthesis:

I am pretty sure that the Porton Down military research facility next to Salisbury is capable or producing it too - but that doesn't mean they produced the specific poison used to attack the Skipals.

The same for VX gas that was used to kill Kim Jong Un's brother in Malaysia. VX was indeed invented by the brits but I would seriously doubt that they killed Kim Jong-Nam.

Edit: this is just factual information. What kind of fscking loosers do downvote this? Go get a reality check.

You're right - any well-equipped state could have synthesized the nerve agent used on the Skripals. But that's not the only evidence: two suspects were identified, who traveled from Russia and stayed at a local hotel. The nerve agent was found in their hotel room.

Of course, you could argue that British intelligence framed those Russians during the investigation, and poisoned the Skripals themselves as some sort of ruse for expelling diplomats. But if you deny the evidence and proceed down that path, you've made the decision not to alter your beliefs and no discussion will change your mind.
