DOWNING Street yesterday defended the appointment of Boris Johnson's chief Brexit negotiator as national security advisor and replaced the "ousted" Sir Mark Sedwill.
The prime minister was criticized for David Frost being a political adviser rather than an official and having no security experience.
He will take on the key role of Sir Mark, who has resigned from reports of clashes with Mr. Johnson's chief adviser Dominic Cummings as cabinet secretary and head of civil service.
Former cabinet secretary Lord O'Donnell said the political candidates were more "yes-men" who told the ministers what they wanted to hear than "telling the truth to the authorities".
"I am concerned about the appointment of David Frost as National Security Advisor because I am not entirely sure how it works to put a special advisor in this role," he told BBC Radio 4 & # 39; s Today.
Downing Street insisted that such appointments were not uncommon in other countries and that Mr. Frost – who has the status of an ambassador – had spent 25 years as a diplomat at the Federal Foreign Office before leaving in 2013. “The first Commissioner for Civil Service has approved the appointment. This is in line with the Constitutional Reform and Governance Act, ”said the Prime Minister's official spokesman.
Lord Kerslake, a former head of public service, accused No. 10 "or the surrounding area" of working to "undermine" Sir Mark. Union leader Sir Keir Starmer said it was "obvious" that the prime minister was determined to get rid of Sir Mark while some MPs suggested that Mr. Cummings was involved in the eviction.
Mr. Johnson denied claims yesterday that his position had been undermined by hostile press conferences.
