Business Secretary urges prime minister’s resignation after former foreign office chief gave incomplete testimony on Mandelson security vetting

On 21 April 2026, senior government minister Kemi Badenoch publicly demanded that Prime Minister Keir Starmer step down, invoking the recent dismissal of former Foreign Office permanent secretary Olly Robbins and the revelation that his evidence to MPs concerning the security‑vetting of former minister Peter Mandelson was, by his own admission, not the whole truth, a development that has now prompted a formal parliamentary hearing chaired by Labour MP Emily Thornberry.

The context of the controversy dates back to the moment Robbins was removed from his post after internal reports linked him to the mishandling of Mandelson’s security clearance, a matter that was first aired in a national newspaper and later revisited when Robbins testified in November of the previous year, at which time Thornberry asserted that his testimony omitted material facts, thereby casting doubt on the integrity of the vetting process and on the mechanisms designed to hold senior civil servants accountable.

In the wake of Thornberry’s criticism, Badenoch’s call for Starmer’s resignation rests on the premise that the prime minister, as head of the Civil Service and ultimate guarantor of national security protocols, bears responsibility for the apparent failure to ensure transparent and comprehensive scrutiny of the Mandelson case, a stance that the prime minister has yet to address substantively, while opposition figures have seized upon the episode as evidence of systemic complacency within the highest echelons of government.

The episode, therefore, foregrounds enduring institutional gaps whereby security vetting reviews can be both politically sensitive and procedurally opaque, exposing a predictable pattern in which senior officials are dismissed without publicly detailed justification, yet their subsequent testimonies remain subject to selective disclosure, a dynamic that not only undermines public confidence but also illustrates the paradox of a system that demands both secrecy and accountability yet appears unable to reconcile the two.
