In the tone London definitely doesn't like.
The Russian ambassador to the UK has claimed Britain played a role in an attack on its warships - warning the country is "too deep" in the Ukraine war. In an interview with Sky's Mark Austin, diplomat Andrei Kelin claimed he had 'proof' that UK special forces were involved in a Ukrainian drone assault on Russia's Black Sea fleet in Crimea and had handed evidence to the British ambassador. ...Pressed to give evidence to the public on Moscow's accusation the attack on the Russian fleet in the Black Sea was carried out under the guidance and leadership of British Navy specialists, Mr Kelin said it had been handed to the British ambassador and added that "it will become public pretty soon," perhaps today, perhaps tomorrow.
One may ask WHY Russia concentrates on UK now, because many speculate that the US was directly involved at least in preparation, not execution, of this act. The answer seems obvious--UK is a disposable asset. Russia and the US are the main parties to the whole geopolitical realignment, UK is not and could be made into the main culprit, because it leaves the door for communications and eventual "settlement" between Russia and US open. This is a classic case of sacrificing a servant to send the message to the master. UK obviously denies all those "allegations", but it doesn't matter since the record has been created and is being filed as I type this.
