European unity over the response to Russia's invasion of Ukraine is proving difficult to maintain in the face of the war's impact on inflation and living standards across the continent, Estonia's prime minister has said.

Kaja Kallas also criticised the French president, Emmanuel Macron, for trying to provide Vladimir Putin with a diplomatic way out of the conflict, saying the only effect was to give the Russian leader the belief that he will not be isolated or face justice for his army's war crimes.
