Former Foreign Office chief Sir Simon McDonald has accused Prime Minister Keir Starmer of throwing Sir Oliver Robbins 'under the bus' by dismissing him as the most senior civil servant in the Foreign Office. McDonald said Robbins was aware of concerns raised during Peter Mandelson's security vetting process but did not inform ministers, leading to the biggest crisis in the diplomatic service in decades.

Why it matters

The dismissal of Sir Oliver Robbins, a top civil servant, over the Mandelson security vetting scandal raises questions about political interference in the civil service and the government's handling of sensitive national security matters.

The details

According to Sir Simon McDonald, Sir Oliver Robbins had been aware of concerns raised during Mandelson's vetting process but did not forward that information to ministers. The Prime Minister stated he was not made aware of the outcome of the vetting process until this week, calling the failure to inform him 'staggering' and saying he was 'absolutely furious' upon learning of it. Sir Simon McDonald told BBC Radio 4's Today programme that Number 10 'wanted a scalp and they wanted it quickly' in response to the scandal.
