Steele dossier alleges Mandelson was Russian intelligence contact
A secret dossier compiled by former MI6 agent Christopher Steele alleges that Lord Mandelson was a privileged contact of Russian intelligence.
The Full Story
A plain summary built from the channels that reported this story.
A secret dossier compiled by former MI6 officer Christopher Steele alleges that Lord Mandelson was considered a privileged contact of Russian intelligence. The dossier, codenamed Project Fish, reportedly states that Moscow's spy masters regarded the Labour peer as one of the most significant achievements of Russian intelligence in manipulating UK politics over the past 30 years.
The claims, first reported by the Telegraph, have been dismissed as nonsense by sources close to Lord Mandelson. They pointed to his public record of opposing Kremlin interests and insisted he did not pass any information to Russia or do anything wrong. The dossier itself does not provide evidence that Mandelson spied for Russia, but it has reignited scrutiny of his past conduct.
Mandelson has previously been criticised for passing market-sensitive information to Jeffrey Epstein before a bank bailout was announced. The new dossier is a private document compiled by Steele after he left MI6, and is the same source that contained unverified allegations about Donald Trump. Steele's team has also indicated they could compile similar dossiers on Boris Johnson, Dominic Cummings, Nigel Farage and Jeremy Corbyn.
The story has drawn attention to the wider issue of Russian intelligence efforts to cultivate contacts among British politicians. The dossier notes that Boris Johnson was monitored by the SVR as a student at Oxford, with files describing him as eccentric but potentially useful, though not trustworthy. Johnson has denied any wrongdoing.
The security implications have been questioned, particularly given that the current Prime Minister, Sir Keir Starmer, was warned about Mandelson's links to Russia, China and Epstein during security vetting, yet still appointed him as US ambassador. Critics argue that vetting after appointment undermines the process.
