Prime Minister Andy Burnham has agreed to give Ukraine the technical blueprints for Britain's Storm Shadow missiles, a move senior security sources say has provoked Moscow. Journalist Dan Hodges reports that intelligence chatter over the past fortnight suggests Russia is preparing some form of retaliatory action against UK interests, seen partly as a deliberate test of the untested Prime Minister's resolve on foreign affairs. Russia's withdrawal of its ambassador from London without a replacement is being read by British security officials as a sign that action may be imminent, since it would leave no diplomat available for the UK to expel in response.

Sources point to several possible scenarios being assessed, including a cyber-attack on infrastructure such as the NHS or transport networks, sabotage of Britain's military supply chain, or a clash between Russian and British forces following recent incidents such as jet interceptions, a jammed RAF navigation system and a Russian frigate's live-fire exercise off Plymouth. There is also concern about a direct provocation targeting Burnham personally, with officials citing last year's firebomb attacks on properties linked to Keir Starmer, reportedly welcomed by Moscow as a successful operation, as a possible template for further action.
