Trump's call with Putin 'a very good early sign' for Ukraine, says UK defence secretary

US media reports suggest president-elect Donald Trump has spoken to Vladimir Putin about the war in Ukraine.

While denied by the Kremlin, The Washington Post and Reuters said Trump - who has previously claimed he'd end the war in a single day - used the phone call to urge the Russian president not to escalate the conflict.

If the reports are correct, UK Defence Secretary John Healey says it's a "very good first step and an early sign" that the incoming Trump administration will stay behind Ukraine.
