Prime Minister Dismisses Connection Between Phone Theft and Mandelson Files
Prime Minister Sir Keir Starmer has firmly rejected suggestions that the theft of his former chief of staff's mobile phone is connected to the release of files concerning Lord Peter Mandelson's appointment as British ambassador to the United States. Speaking to journalists in Helsinki, Starmer described such theories as "a little bit far-fetched" and insisted the incident was a straightforward criminal matter.
Timing and Official Response
The mobile phone belonging to Morgan McSweeney, who served as the Prime Minister's chief of staff until last month, was stolen in London during October 2025. This occurred several months before Members of Parliament compelled the government to release correspondence related to Lord Mandelson's controversial diplomatic posting. Downing Street has been keen to emphasize this timeline, with the Prime Minister's official spokesman stating: "The idea that the theft was connected to the humble address is categorically untrue."
Health Secretary Wes Streeting has characterized the loss of messages as a "cock-up rather than conspiracy," while the government maintains its commitment to fully comply with parliamentary requests for document disclosure. All relevant departments and individuals have been instructed to provide all information within the scope of the humble address motion.
Security Concerns and Political Reactions
Opposition leader Kemi Badenoch has expressed suspicion about the timing of the theft, telling broadcasters in London: "It is very suspicious that the phone got stolen after it became clear that a lot of documents were going to come out." The Conservative leader suggested the theft could have involved foreign actors and called for greater transparency from both McSweeney and Starmer regarding why the incident wasn't escalated to security services.
Even within Labour ranks, questions have emerged. Kingston upon Hull East MP Karl Turner has publicly referred to McSweeney as "McSwindle," while fellow Labour backbencher Richard Burgon has submitted formal parliamentary questions about whether proper protocols were followed regarding the theft's reporting, data backup procedures, and potential national security implications.
Investigation Details and Document Status
Police have taken the unusual step of releasing a transcript of McSweeney's 999 call reporting the theft. During the call, he provided his name, personal email address, a home address outside London, and confirmed the device was a government phone. However, a geographical error occurred when McSweeney incorrectly stated his location as Belgrave Street rather than Belgrave Road, leading police to check incorrect CCTV footage and initially conclude there were no viable investigative leads. This aspect is now under review.
Concerns have been raised because the phone wasn't backed up, resulting in the loss of correspondence. Nevertheless, the Cabinet Office is understood to possess some messages exchanged between McSweeney and Lord Mandelson. The first batch of documents related to Mandelson's appointment was published earlier this month, with additional releases expected to follow.
Background Context
Lord Mandelson, a political appointee rather than career diplomat, was dismissed from his Washington ambassadorship in September last year due to his associations with convicted paedophile financier Jeffrey Epstein, who died in 2019. MPs moved in February to force publication of tens of thousands of documents amid questions about what was known regarding Mandelson's Epstein links before he received the prestigious diplomatic posting. McSweeney's departure from Downing Street last month followed criticism that he had championed Mandelson's controversial appointment.
