PFR,
Any truly intelligent observer would be sceptical of both Russia and the UK Govt...

So you do not regard as intelligent the governments of every EU nation, Canada, Australia and all the other well informed liberal democracies.

I do. They have seen the evidence and they know who to believe.

Steve,
So to sum up, what we've "found out" today is that novichok was used and that novichok was developed in Russia. Well blow me down!

Also that it was highly purified, and that the British were honest and accurate in their analysis.
What we "found out" is not the whole story anyway.

I'd really appreciate it if someone could tell me how I'm supposed to connect those two facts in my tiny brain.

You are not. There is evidence not released.
The real scientists are able to make that connection, and have.
