Any move to “wipe the slate clean” for Russia in a peace deal would be “a historic mistake of huge proportions,” the EU justice commissioner tells POLITICO.

Donald Trump’s drive to secure peace in Ukraine must not let Vladimir Putin off the hook for war crimes committed by Russian forces, a top EU official has warned, effectively setting a new red line for a deal.

In an interview with POLITICO, Michael McGrath, the European commissioner for justice and democracy, said negotiators must ensure the push for a ceasefire does not result in Russia escaping prosecution.

His comments reflect concerns widely held in European capitals that the original American blueprint for a deal included the promise of a “full amnesty for actions committed during the war,” alongside plans to reintegrate Russia into the world economy.
