Lord Mandelson has repeatedly said he regrets his relationship with Epstein, who died in jail in 2019 while awaiting trial on sex trafficking offences.
Turner said he was “honoured” to be nominated for the role.
“At a pivotal time for the transatlantic relationship, I look forward to working with President Trump’s administration, and leaders in Congress, business and society to strengthen that bond in the years ahead,” he added.
In a statement released by the Foreign Office, Starmer said: “The United Kingdom and United States have a very special relationship, and Christian’s extensive experience as an outstanding diplomat will support this uniquely close bond and ensure it continues to flourish.”
Turner’s previous roles include political director at the Foreign Office, and British High Commissioner to Pakistan. He also previously worked in 10 Downing Street as Private Secretary to the Prime Minister.
Before entering government, he worked in television documentaries.
