Political pressure continues to mount on UK Prime Minister Keir Starmer in Parliament, as a Conservative MP has presented new evidence accusing him of ignoring serious national security risks in appointing Peter Mandelson.

Controversial Links to Russia

Speaking in the House of Commons, Conservative MP Katy Lamb pressed the Prime Minister over the intelligence he had received prior to making the appointment.

At the centre of her challenge was Mandelson’s role at Sistema, a major Russian corporation with significant ties to the country’s military-industrial complex. According to Lamb, Mandelson served as a director at Sistema from 2013 until at least June 2017—remaining on the board well after Russia’s annexation of Crimea in 2014.

She further argued that this position placed him in close contact with senior Russian figures, including former Sistema chairman Vladimir Yevtushenkov, who has since been sanctioned over alleged links to Vladimir Putin.

Ignored Security Warnings and Misleading Claims?

Lamb accused Starmer of disregarding clear security warnings. She pointed out that in November 2024, the Cabinet Secretary had advised that candidates for sensitive diplomatic roles—such as the post in Washington—should undergo security vetting before appointment. Despite this, Starmer proceeded with Mandelson’s appointment in December 2024.

By January 2025, the Prime Minister repeatedly told the media and the public that Mandelson had “passed security checks,” which, Lamb claimed, was not accurate. She added that briefing documents provided to Starmer in December 2024 had explicitly highlighted Mandelson’s links to Sistema, yet he had twice refused to confirm whether he was aware of this information during previous parliamentary sessions.

Demand for Transparency

Concluding her intervention, Lamb demanded a clear “yes or no” answer as to whether the Prime Minister had considered the Russia-related risks before making the appointment.

“Either the Prime Minister is still reluctant to share with us the information we deserve to know, or he did not bother to read the briefing he was given,” she stated sharply. “The public cannot believe that he failed to ask any questions at all.”

The controversy further deepens the growing crisis of confidence surrounding Keir Starmer’s leadership, particularly in handling sensitive issues of national security and high-level diplomatic appointments.
