Justice Secretary Dominic Raab is off to the International Criminal Court in The Hague on Monday to help arrange the prosecution of Vladimir Putin for war crimes.
The Deputy PM will aim to bring together a coalition of countries to gather enough evidence to indict the Russian president.
Mr Raab said: “I will offer UK technical support in bringing those responsible for war crimes in Ukraine to justice.
“Russian commanders carrying out war crimes should know they cannot act with impunity.”

He will tell them specialist police and military help from Britain will be on hand to build a case against Putin.
And he will say that witnesses who fear for their lives will be given sanctuary in the UK
