Downing Street has appointed a new National Security Adviser days before Lord David Frost was due to start.
The chief Brexit negotiator was meant to take up the post on Monday, but will now be replaced by the Ministry of Defence’s Sir Stephen Lovegrove.
No 10 faced criticism over Lord Frost’s appointment in June last year, with former PM Theresa May saying he had “no proven expertise” in the area. Now he will be the PM’s representative on Brexit and International Policy.
A statement from Boris Johnson did not explain why Lord Frost was changing roles. But the prime minister said he was “thrilled” Lord Frost had accepted the new post, and that Sir Stephen would bring “a wealth of experience from across Whitehall and in national security”.
