Government officials face stark warning over handling of sensitive Mandelson messages
In a move aimed at preventing further embarrassment for Westminster, the Cabinet Office has issued a stern warning to ministers not to release private WhatsApp exchanges with disgraced former ambassador Peter Mandelson. The message came after Labour MP Wes Streeting released dozens of messages exchanged between August 2024 and October 2025, sparking concerns about the handling of sensitive information.
The Met police investigation into allegations of misconduct in public office following claims that Mandelson passed market-sensitive information to Jeffrey Epstein when he was business secretary is ongoing. The police have emphasized the importance of due process being followed, with one spokesperson stating: "It's vital we follow due process so our criminal investigation and any potential prosecution isn't compromised."
In light of this, Cabinet Office officials have advised against sharing material that could be covered by a Commons motion forcing the release of documents related to Mandelson's appointment as US ambassador. This warning comes amid growing calls for greater transparency over the government's handling of sensitive information.
Meanwhile, Keir Starmer faced scrutiny over his response to Streeting's decision to release his own messages unilaterally. The Labour leader emphasized the need for a "managed process" in releasing information related to Mandelson, suggesting that all parties involved must act together to ensure justice is served.
As the investigation into Mandelson's alleged misconduct continues, officers have searched two properties connected to him as part of their inquiry. The Met police are reviewing documents identified by the Cabinet Office and working with government officials to determine which documents should ultimately be published.
The handling of sensitive information in this case highlights ongoing concerns about transparency and accountability at Westminster.
