The split in the room
This is a voluntary appearance. Robbins is no longer a serving civil servant; he was effectively fired on Thursday night after Downing Street and the Foreign Secretary “lost confidence” in him. He is understood to be bruised, to be upset at the personal criticism, and to have retained his own counsel. Voluntary witnesses are not bound by the Civil Service Code in the way serving officials are — he can answer the political questions the Cabinet Secretary would otherwise have asked him to stay away from. That is why he agreed. That is also why Downing Street did not want this hearing.
The session is chaired by Priti Patel, who has her own long-running grievance with the Foreign Office establishment and has spent the weekend circulating among committee members. The briefing pack runs to fourteen pages. The submitted documents include the January 2025 UK Security Vetting report refusing Mandelson developed vetting clearance and the 48-hour override memo signed by an FCDO official still in post. The pack identifies three separate moments at which the Prime Minister’s private office was copied on correspondence — a data point Downing Street has, so far, not addressed.
The one question that matters
Committee members have coordinated around a single central question: did the Prime Minister, or anyone in his direct office, see or receive briefing on UK Security Vetting’s refusal of Mandelson in January or February 2025? Every subsidiary line of enquiry — who signed off on the FCDO override, what the Foreign Secretary knew, why a former Permanent Secretary lost his job — leads back to that one answer. Starmer said in the Commons on Monday that he only learned UKSV had declined approval “the previous Tuesday.” If Robbins confirms that claim, the Prime Minister is bruised but survives. If Robbins contradicts it — either directly, or by producing evidence that the PM’s office was copied — the Commons has a contempt of Parliament question to answer within forty-eight hours.
Kemi Badenoch has already referred the matter to the Privileges Committee. The Privileges Committee cannot sit on a referral while a related Select Committee is taking evidence. The timing of Tuesday’s session is therefore the moment at which the procedural question becomes inescapable.
What Robbins is expected to say
Those close to Robbins have briefed that his objective is not to survive in public life — he has a £100,000 compensation package and a reputation at stake rather than a career — but to establish for the record that he did what senior civil servants are obliged to do. That is: he briefed the Foreign Secretary’s office on the vetting refusal, he raised the issue at permanent secretary level, and he believed that his obligation to brief the Prime Minister was discharged through those channels. Whether he also briefed No. 10 directly is the question the committee will press on hardest.
Three lines to watch for. First, any reference to a written note. Robbins is a known paper-generator; if he wrote a minute in January or February 2025 identifying the override, that minute is discoverable. Second, any reference to having been told by a named senior official to stop raising the issue. The Foreign Affairs Committee can compel that official to return. Third, any reference to Jonathan Powell, the National Security Adviser, a former Blair chief-of-staff who was famously close to Mandelson. Powell is not in the press coverage tonight. His name is in the briefing pack.
How Downing Street plans to play it
Starmer is chairing Cabinet at 9.30am. He will not watch the opening half hour of Robbins’ evidence live. The Prime Minister’s press team has pre-briefed the line that any contradiction between Robbins and No. 10 is a difference of recollection and does not rise to the level of parliamentary misleading. Privately, two of the most senior figures in the Cabinet spent Monday night telling lobby journalists they are not confident that line holds. Yvette Cooper, whose own departmental letters are in the briefing pack, has been uncharacteristically silent.
The recess is the friend Downing Street spent last week praying for. Tuesday morning is the last working day before the Commons rises on Wednesday for the local election campaign. If Robbins lands a single clean contradiction, the story runs hot through the campaign weeks with no Commons chamber available to defuse it. If he does not, the political heat dissipates into the campaign. Nobody at the Foreign Office is confident which way the next two hours break.
