Sir Olly Robbins Files Judicial Review Challenging Dismissal Over Mandelson Vetting Scandal

The FDA union argues the Prime Minister has no statutory authority to dismiss the Head of the Diplomatic Service and that the dismissal was conducted without a fair procedure.
The National Security Vetting system is described as operating independently of government ministers, with ministers only informed of the final outcome, and a 16 September 2025 Foreign Secretary letter indicates No.10 drafted the text.
Downing Street said the Foreign Office overruled a vetting decision without informing Sir Keir Starmer, David Lammy or any No. 10 officials.
It emerged that Mandelson's appointment as US ambassador was approved despite awareness of his friendship with Jeffrey Epstein, adding fuel to scrutiny of the vetting process.
Robbins said he brings the action reluctantly and that the Prime Minister's decision caused distress and cost to him and his family, leading to a court challenge.
Sir Olly Robbins, the former head of the Foreign Office, has filed a judicial review challenge against his sacking by Prime Minister Sir Keir Starmer, according to LBC and The Independent. Robbins was dismissed after Downing Street claimed he failed to tell the Prime Minister that Lord Mandelson had not passed security vetting before being appointed British ambassador to the United States.
Robbins said he brings the case "reluctantly" but argues the decision was unnecessary and caused "distress and cost" to him and his family. He wants a court to declare the sacking unlawful and quash it entirely.
The controversy centres on Lord Mandelson's security vetting for his US ambassador role. Downing Street says the Foreign Office overruled a vetting decision without telling Sir Keir Starmer, Foreign Secretary David Lammy, or anyone at No. 10, according to LBC. Robbins, as Permanent Under-Secretary, was held responsible for that failure to inform the Prime Minister.
Adding to the pressure, it also emerged that Mandelson's appointment went ahead despite officials knowing about his friendship with convicted sex offender Jeffrey Epstein. That detail has sharpened public and political scrutiny of how the vetting process was handled from the start, according to Yahoo News.
The FDA, the union representing senior civil servants, is backing Robbins's legal challenge. The union argues that the Prime Minister simply does not have the legal authority to dismiss the Head of the Diplomatic Service. It says no proper or fair procedure was followed before the sacking, according to The Independent.
The FDA calls the dismissal a breach of principle. Civil servants at that level are meant to have protection from direct political removal. The union's argument, if accepted by a court, could set a significant precedent for how senior officials can be treated by ministers.
The National Security Vetting system is designed to work independently of government ministers. Under the normal process, ministers are only told the final outcome — pass or fail — not the details behind it. This means ministers do not directly control or override vetting decisions, according to Yahoo News.
A letter from the Foreign Secretary dated 16 September 2025 has added a further twist. It emerged that No. 10 itself drafted the text of that letter, raising questions about whether the government's public account of events was shaped from the top, according to LBC.
Robbins is asking a court to declare the Prime Minister's decision unlawful and to formally quash it. He says he did not want to go to court but felt he had no choice. The case is now part of a wider picture of questions about political independence in the civil service, according to The Independent.
The judicial review process means a judge will examine whether the decision was made lawfully and with a fair process. If Robbins wins, the sacking could be overturned. The case is being watched closely in Whitehall as a test of how far a Prime Minister's power over top officials actually stretches, according to LBC.
