Can Ukraine recruit enough soldiers to maintain its defence against Russia? This week, parliament is expected to debate a new version of an already-delayed mobilisation bill. After almost two years of war, the men sent to the front line are exhausted. Most Ukrainian soldiers have had fewer than 10 days’ leave in the past year. The mobilisation bill proposes limiting military service to three years, but also reducing the conscription age from 27 to 25 and tightening penalties for those who fail to register. The legislation is proving divisive in Ukraine, as our correspondent Gulliver Cragg reports.
