Cabinet Office postpones Starmer’s briefing on Mandelson vetting recommendation for nearly three weeks

The permanent secretary of the Cabinet Office, Cat Little, told Parliament that she deliberately sought legal advice before passing on a Foreign Office recommendation to grant former minister Peter Mandelson security vetting, a step that ultimately resulted in a delay of almost three weeks before Prime Minister Keir Starmer was informed, a timeline that suggests a puzzling reluctance to comply with a humble address without additional justification.

In early March, Little requested access to the Foreign Office’s documentation concerning the decision to grant Mandelson vetting, explicitly invoking the humble address as the legal basis for her request, only to be informed that the requested material would not be forthcoming, an answer that prompted her to schedule a meeting with Sir Oliver and a senior member of his team mid‑month in order to confirm the existence of a summary document she had been told existed.

During that meeting, Little again asked to see both the summary document and any audit trail that recorded the judgments underlying the vetting decision, receiving the same refusal that the information would not be provided, a response that compelled her to take the unusually proactive step of contacting UK Security Vetting directly, a move she justified on the grounds that discharging the humble address constituted a unique responsibility that she “takes very seriously.”

The sequence of refusals, the inter‑departmental tug‑of‑war, and the ultimate reliance on a direct request to the security vetting authority illustrate a procedural inconsistency that not only delayed a crucial briefing to the prime minister but also exposed a systemic gap in the mechanisms designed to ensure timely parliamentary oversight of sensitive security clearances.

While Little’s eventual action in bypassing the usual chain of command may be praised as a determined effort to fulfill her statutory duties, the three‑week lag between the initial recommendation and the prime minister’s receipt of the information underscores a broader institutional failure to reconcile legal obligations with bureaucratic inertia, raising questions about the effectiveness of existing protocols for handling high‑profile vetting decisions in a timely and transparent manner.
