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 was appointed by Theresa May as Cabinet Secretary in October 2018, the highest position in Whitehall, succeeding Jeremy Heywood who was diagnosed with lung cancer And died in November 2018. Sedwell has served as a national security adviser since April 2017. It was the highest official of the Ministry of the Interior in May.
Downing Street said that when the United Kingdom takes over as chairman of the international group next year, Sedwell will assume the new role of leading the “Group of Seven on Global Economic Security.”
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.”
Sedwell thanked Johnson for his trust and friendship with the Foreign Secretary and Prime Minister.
Johnson is expected to give a speech on Tuesday to clarify the government’s plan for the recovery of coronavirus. In his reply to Sedwell, the Prime Minister said: “In the past few years, I have direct experience with your excellent service to the government and the entire country.
“It is a huge contribution by any standard, but as Prime Minister, I especially appreciate your calm and shrewd advice.”
Johnson welcomed Frost in his new position in another statement. 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.”
Frost said he will continue to serve as the chief negotiator for Brexit until the negotiations on the future relationship between the UK and the EU have ended. The transition period after Brexit will end on December 31, when the UK hopes to negotiate a free trade agreement with the EU.
