Britain is to step up military aid to Ukraine as Boris Johnson warned Vladimir Putin could still seek to “twist the knife” despite Russia’s faltering campaign.

The UK Chief of the Defence Staff, Admiral Tony Radakin, told the Cabinet that Britain’s support was moving to a “new phase” as the Ukrainians sought to retake territory captured by the Russians.
