The head of the British intelligence service (GCHQ), Anne Keast-Butler, said on May 27 that since the beginning of the full-scale war in Ukraine, almost 500 thousand soldiers of the army of the aggressor country, Russia, have died at the front. She was quoted by The Guardian.
A high-ranking British official confirmed for the first time the British assessment of Russian losses in Ukraine, the publication noted.
Keast-Butler reported that the illegitimate Russian President Vladimir Putin is “retreating to the battlefield,” and the permanent losses of the occupiers, according to intelligence data, reach almost half a million people.
At the same time, the head of GCHQ noted that, in the fifth year of the war, Russia is expanding the scope of its hybrid activities against the UK and Europe, aimed at the seabed, cyberspace, critical infrastructure, democratic processes, supply chains and public trust. British intelligence works with partners to prevent such threats, she stressed.
The Russian publications Meduza and Mediazona, in a joint study published in early May, wrote that as of the end of 2025, more than 350 thousand Russians had died in Ukraine.
US Secretary of State Marco Rubio, in an interview with Fox News, which was published on May 14, said that the Russians are losing five times more soldiers per month than the Ukrainians.
