Rishi Sunak has demanded Vladimir Putin “get out of Ukraine and end this barbaric war”.
The PM was pictured glowering at Russian foreign minister Sergei Lavrov as they came face-to-face at the G20 summit in Indonesia.
In his address to world leaders, Mr Sunak rebuked Moscow by saying "countries should not invade their neighbours".
The gathering on the island of Bali is the first time a British PM has met a representative of the Kremlin since it started the war in Ukraine.
Putin has chosen not to attend the event and has sent his right hand man, Lavrov, instead.
