The trial, which would be modelled on the Nuremberg trials where 161 war criminals were prosecuted after the Second World War, would act in addition to the current investigations into war crimes by the International Criminal Court (ICC).
The campaign, launched last week, is supported by the Ukrainian President Zelensky and Minister of Defence, Dmytro Koleba, professor of international law Philippe Sands QC, former prosecutor for the Nuremberg Military Tribunal Benjamin Ferencz, Helena Kennedy QC, and Sir Nicolas Bratza, former President of the European Court of Human Rights.
An accompanying petition has gained more than 1,348,000 signatures. It calls on world leaders to hold Putin and his accomplices personally accountable by creating a special tribunal for the punishment of the crime of aggression, and to fully support the ICC’s separate investigation into alleged war crimes and crimes against humanity.
Brown said: ‘From Britain, which rightly prides itself in democracy and the rule of law, the message must go out.
‘At Nuremberg we held the Nazi war criminals to account. Now, eight decades on, we must ensure there will be a day of reckoning for Putin.’

Meanwhile, the Charity Commission has published guidance aimed at charities and trustees that are responding to the conflict in Ukraine. It includes information on fundraising and Ukraine appeals, setting up a new charity, changing charitable objects to support the Ukraine crisis, safeguarding, compliance with financial sanctions and participation in aid convoys.
The commission suggests supporting local economies by buying goods close to the point of need rather than arranging aid convoys. Read the guidance here.
