Russia may have lost a third of the invasion force it sent into Ukraine as its offensive continues to struggle in the face of stiff resistance, British military intelligence has said.

In its latest assessment, the Ministry of Defence (MoD) said the Russian campaign in the east of Ukraine had “lost momentum” and was now “significantly behind schedule”.
