War in Ukraine: Gordon Brown backs Nuremberg-style trial for Putin
Gordon Brown and Sir John Major want a new international tribunal to be set up to investigate Vladimir Putin for his actions in Ukraine.
The former PMs are among 140 academics, lawyers and politicians to sign a petition calling for a legal system modelled on the Nuremberg trials of Nazi war criminals after World War Two.
The International Criminal Court (ICC) is already investigating Mr Putin for alleged war crimes in Ukraine.
