Russia has lost around 15,000 troops since the beginning of the war in Ukraine, according to the UK Defence Secretary.
Ben Wallace told MPs in the Commons that Moscow has also thousands of armoured vehicles, tanks, helicopters and fighter jets in the conflict.
The huge death toll was evidence of how badly the war is going for Vladimir Putin, said Wallace, with a quarter of Russian fighting units now rendered not combat effective by the fierce resistance being put up by the Ukrainian forces.
