Putin is gambling on the west growing impatient with Ukraine. We have to prove him wrong | Jonathan Freedland

A year into his country's fight for its very survival, Volodymyr Zelenskiy knows some in Europe are looking for a way out

The image was stunning, the optics perfect: a war leader addressing the nation in an ancient hall, the rays of stained-glass sunlight all but crowning him with a halo. And yet there was something wrong with that picture. Volodymyr Zelenskiy was not stiffening the resolve of his own people, who after a year of war, bereavement and pain might be forgiven for losing heart. Rather, he was in Westminster to steady the nerves of British politicians - and, later, European ones - to ensure they do not abandon a fight that has cost them so much less.

His official request was for fighter planes - Give us wings," he said - but he had a wider purpose. His lightning trip to London, Paris and Brussels was aimed at ensuring the west does not grow impatient, that as the first anniversary of Vladimir Putin's invasion of Ukraine approaches, it does not start looking at its watch - and for an early way out.
