“I am also delighted to appoint Sir Stephen Lovegrove as my National Security Adviser. Stephen brings with him a wealth of experience from across Whitehall and in National Security and I look forward to working closely together to deliver this Government’s vision for the UK in the world.”

Lord Frost said: “I am delighted to take up this new role as the Prime Minister’s Representative on Brexit and International Policy. With a new agreement with the EU in place, we have huge opportunities to boost our wealth and define what we stand for as a country internationally, and I very much look forward to supporting the Prime Minister on this.”

Sir Stephen Lovegrove said: “It has been an immense privilege to serve as the Permanent Secretary at the Ministry of Defence for the past five years. Working with the whole force – our armed forces, both regular and reserve, civil servants, our suppliers and everyone that makes up the Defence community – has been an honour.

“I am delighted now to be taking up the role of the National Security Adviser. On this broader canvas I aim to deliver the Prime Minister’s vision for an enhanced and more engaged role for the UK in the world, leading the national security community to embrace the opportunities now available to us, while ensuring we are well prepared to deal with the challenges we face.”
