Can the British Parliament Arrest Putin if he is found guilty of a war crime?

Dominic Raab has suggested that if Putin is found guilty of war crimes, then Britain is ready to jail him.

Dominic Raab, the Deputy Prime Minister, and the Justice Secretary, has warned Vladimir Putin that he can stay in the British prison cell if he is found guilty of war crimes. He also stated that Putin’s generals could also be imprisoned in Britain. The jail cells are ready and are waiting for them.

It is estimated that Putin could well stand in the dock at the Hague, where he will face a trial for “slaughtering innocent civilians.” It is important to note that Russia is currently under investigation by the International Criminal Court for war crimes.

Also, British Prime Minister Boris Johnson has already accused the Russian president of committing such crimes as he has dropped cluster bombs on blocks of flats in Ukraine, which has resulted in killing many innocent lives.
