David Frost, the UK’s chief Brexit negotiator and Johnson’s close ally, will take over as national security adviser, and the government will soon begin to search for Sedwell’s successor as cabinet secretary and head of civil service affairs.

Sedwell said in his resignation letter to the Prime Minister: “Two years ago, when my predecessor fell ill, your predecessor asked me to serve as the cabinet secretary. You asked me to continue supporting you during Brexit and the election. Obviously, It is right to continue to participate in the severe phase of the Covid-19 crisis. As you mentioned this week, the government’s focus is now shifting to domestic and global recovery and renewal.”

He said: “I have asked David to help me realize the government’s vision of Britain’s position in the world and support me in revitalizing our national security architecture, and Make sure we serve the UK. People on the international stage.”
