David Cameron's former chief of staff has been appointed ambassador to France, the Foreign Office has announced.
Ed Llewellyn, who was made a life peer in the former Prime Minister's resignation honours list, will take up the posting in November.
Foreign Secretary Boris Johnson said: "Ed Llewellyn is hugely well qualified for this post and I look forward to working with him.
"He will help us make a great success of Brexit while ensuring that Britain is more engaged in the continent of Europe than ever."
Downing Street confirmed that Theresa May - who has been accused of attempting to dismantle Mr Cameron's legacy - approved the appointment.
"At an important time for relations between our countries, the PM firmly believes he will bring substantial political and diplomatic experience to the role," a No 10 spokesman said.
"The PM is confident that Ed will approach the role with his trademark energy, commitment and professionalism and wishes him well as our new ambassador to Paris."
