Yes, the D Notice is particularly interesting. I agree regarding censorship on our part.
I remember at the time of the Skripal fantasy, Lavrov commenting about the UK govt. quoted from Alice's Adventures in Wonderland,
"Verdict first, evidence later"
How apt. Lavrov knows his history and understands the ways of the "Perfidious Albion".
There were also "D notices" in place forbidding mention of certain persons in the Skripal farce, that we know of for certain, and in light of this it begs the question of just how many "D notices" have been issued in the last few years. It is also a curious coincidence that whenever there are allegations against the Russian state, UK intel and "D notices" seem to pop up. It has been going on for some time, the provocations against Russia.
This new stage goes beyond provocations. UK/US and NATO are insanely criminally irresponsible now using their populations as pawns in their desperation to subdue Russia.
This time it appears that the UK govt. have waged an undeclared war and via "D notices", censorship and outright lies are seeking a casus belli.
This is extremely serious and by the actions of the UK state it is clear, at this point, that decisions of such magnitude are taken to serve someone other than the UK public. A functioning democracy with a free press would rid themselves of such vile warmongers. Alleged "Russian aggression" is going to be reported regardless of there actually being any.
Verdict first, evidence later evolves into
War first, casus belli later.
