The government has agreed to strengthen checks on people proposed for direct ministerial appointments to senior diplomatic posts following a parliamentary investigation into Peter Mandelson’s appointment as British ambassador to the United States.
In a response published on 16 October 2026, the Foreign, Commonwealth and Development Office (FCDO) accepted several recommendations from the House of Commons Foreign Affairs Committee, while leaving some questions about national security vetting to a separate review.
New checks for ministerial appointments
Under the government’s response, names proposed for direct ministerial appointment by the Prime Minister or Foreign Secretary will be shared with the FCDO’s Permanent Under-Secretary. The department will carry out open-source due diligence, discuss identified risks with the candidate and provide ministers with advice about managing or mitigating those risks.
Due diligence reports will also be shared at an appropriate level with the hiring department, which will have an opportunity to contribute to the process.
MPs seek a role before appointments are made
The FCDO has also welcomed discussions with the Foreign Affairs Committee about a possible new process for parliamentary pre-appointment scrutiny of political candidates for head-of-mission roles.
Committee chair Dame Emily Thornberry has asked Foreign Secretary Ed Miliband to nominate officials by 22 October to begin working with parliamentary staff on the details.
That discussion is not yet an agreed system of parliamentary hearings, and the government has not committed to giving MPs a veto over diplomatic appointments.
Security vetting questions remain
The government has deferred its response to the committee’s recommendations concerning the National Security Vetting system pending the review led by Sir Adrian Fulford.
Thornberry welcomed the prospect of greater scrutiny but questioned the delay in publication of the separate vetting review. The committee’s earlier report examined the circumstances surrounding Mandelson’s appointment and the handling of vetting information.
What happens next?
The immediate changes concern departmental due diligence and the sharing of risk assessments. Any additional parliamentary scrutiny arrangements will need to be developed through discussions between the Foreign Office and MPs, while the separate national security vetting review remains outstanding.
