Andrei Fedorov, an advisor to the Russian government, has warned of a potential semi-military response against British drone factories by unidentified sources in response to the UK's decision to share blueprints for components of its cruise missiles. The threat comes after UK Prime Minister Andy Burnham announced plans to visit the US next month to discuss Ukraine's defense needs with President Trump. The sharing of blueprints for British-made Scalp missile components, a French variant of the UK's Storm Shadow cruise missile, will enable Ukraine to produce the long-range weapon domestically. Fedorov, formerly Russia's deputy foreign minister, suggested that the pressure for such a response was coming from public opinion polls, journalists, and mass media. He did not rule out the possibility of attacks on drone factories being carried out by unknown sources rather than directly by Russia. The Kremlin spokesman Dmitry Peskov had earlier criticized the UK's decision to share missile blueprints, stating it prevented "even the slightest progress" towards achieving peace. In response, Burnham reaffirmed the UK's support for Ukraine amid escalating Russian strikes in recent weeks and emphasized that the UK would not back down until there is a just and lasting peace. This was Burnham's first official international visit since becoming prime minister in July, during which he met Ukrainian President Volodymyr Zelensky and chaired his first meeting of the "coalition of the willing." The UK has been under pressure to supply Ukraine with Patriot interceptor missiles due to dwindling American supplies and growing vulnerability to Russian attacks. However, Burnham expressed confidence that a solution involving multiple layers and negotiations could be found to address this issue. In July, former President Trump had backtracked on an offer to allow Ukraine to produce Patriots itself, citing concerns over giving away such advanced technology.
