By Global Leaders Insights Team | Dec 19, 2025
The United Kingdom has appointed senior career diplomat Christian Turner as its next UK ambassador to the United States, according to media reports citing government sources.
The move comes as Prime Minister Keir Starmer government seeks to reinforce UK-US relations following recent diplomatic disruption.
Turner, who had been expected to take up the role of Britain’s ambassador to the United Nations, will instead be posted to Washington as British ambassador Washington.
He replaces Peter Mandelson resignation, who stepped down earlier this year after controversy surrounding previously undisclosed links with convicted sex offender Jeffrey Epstein. Mandelson’s resignation left a key diplomatic post vacant at a time of heightened geopolitical tension.

The UK government said Turner’s appointment reflects the importance London places on its UK foreign policy priorities and the US-UK special relationship, particularly on defence, trade, technology cooperation and global security. Starmer described Turner as a highly experienced diplomat with a deep understanding of international affairs and crisis management, underscoring the significance of the UK diplomatic appointment.
Turner has spent nearly 30 years in the British diplomatic service. His previous roles include serving as high commissioner to Kenya and Pakistan, as well as holding senior positions within the Foreign Commonwealth Development Office. He has worked closely on security policy, multilateral diplomacy and bilateral relations across Africa, Asia and the Middle East, contributing to broader UK international relations.
In a brief statement, Turner said it was an honour to be appointed ambassador to the United States and that he looked forward to strengthening UK-US defence cooperation and economic engagement. He noted that the partnership remains central to addressing shared global challenges through sustained diplomatic engagement at the UK Washington embassy.
The appointment comes amid a complex phase in UK ambassador news coverage under President Donald Trump’s administration, marked by cooperation on defence and intelligence alongside differences on trade, climate policy and freedom of expression. Analysts say appointing a career diplomat signals a return to institutional continuity.
