MI6 spy boss Sir Richard Moore has appealed to Russians shocked by Vladimir Putin's atrocities in Ukraine to cooperate with the UK's intelligence providers and assist put a cease to the warfare.

Sir Richard made disclosed throughout his lecture in Prague, Czech Republic, that "many" Russians have already taken this step and partnered with the UK since Russia's invasion of Ukraine started 18 months in the past.

He mentioned: "There are many Russians today who are silently appalled by the sight of their armed forces pulverising Ukrainian cities, expelling innocent families from their homes and kidnapping thousands of children."

"They are watching in horror as their soldiers ravage a kindred country. They know in their hearts that Putin's case for attacking a fellow Slavic nation is fraudulent, a miasma of lies and fantasy."

Sir Richard added "many Russians are wrestling with the same dilemmas and the same tugs of conscience" as their predecessors did in 1968 when Soviet tanks crushed the Prague spring uprisings.

"I invite them to do what others have already done this past 18 months and join hands with us. Our door is always open," he mentioned.

"We will handle their offers of help with the discretion and professionalism for which my service is famed. Their secrets will always be safe with us.

"And collectively we are going to work to convey the bloodshed to an finish."
