The United Kingdom has appointed veteran diplomat Christian Turner as its new ambassador to the United States, replacing Lord Peter Mandelson, Downing Street has confirmed.
Turner, a career Foreign Office official with almost three decades of experience in Whitehall and abroad, will take on one of Britain’s top diplomatic roles at a crucial time in transatlantic relations. His appointment follows the departure of Mandelson, who was ousted by Prime Minister Sir Keir Starmer after evidence emerged that he remained linked to the late Jeffrey Epstein.
The Foreign Office said King Charles had formally approved Turner’s appointment and the UK was now seeking the usual approval from Washington. In a brief statement, the White House said it looked forward to working with Turner to “further strengthen the strong relationship between the United States and the United Kingdom.”
Turner said he was “honored” to be nominated, adding that the timing of the role underscored its importance. “At a crucial time for the transatlantic relationship, I look forward to working with President Trump’s administration and congressional, business and civic leaders to strengthen this bond in the years ahead,” he said.
His arrival in Washington comes as relations between Britain and the US face a series of diplomatic tests. Chief among them is Donald Trump’s push for a quick resolution to the war in Ukraine, a stance that has unsettled European leaders who fear that a quick resolution could jeopardize the continent’s long-term security. Turner must also work with Washington on a long-awaited technology deal that has been delayed amid criticism of Britain’s online security regime by some U.S. lawmakers and officials.
Earlier this month, a U.S. national security strategy document signed by Trump warned that Europe was facing the “extinction of civilization” and questioned the reliability of certain allies. It was emphasized that Turner has to find his way in an increasingly complex environment.
Sir Keir Starmer has sought to maintain close ties with the Trump administration, including hosting the US president for a second state visit in September, during which Trump spoke of the “unbreakable bond” between the two countries. However, Mandelson’s abrupt departure a few days before that visit underscored the political sensitivity associated with the ambassadorship.
Turner’s background is firmly rooted in diplomacy. His previous positions include Political Director at the Foreign Office, British High Commissioner to Pakistan and Director for the Middle East and North Africa. He also served as Private Secretary to the Prime Minister at No. 10. Before taking office, he worked in television documentaries.
Sir Keir said Turner’s appointment reflected the importance of the role. “The United Kingdom and the 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 thrive,” he said.
Secretary of State Yvette Cooper added that Turner would bring “exceptional diplomatic experience and deep understanding” to the post. The role of Ambassador to Washington is widely regarded as one of the UK’s most influential diplomatic appointments, carrying significant political, economic and security responsibilities.
