James Paul Roscoe (born 1976) is a British diplomat who has served as the Deputy British Ambassador to the United States since July 2022.
He previously served as British Chargé d'affaires ad interim to the United States in February 2025 between the departure of Karen Pierce as British ambassador and the appointment of Peter Mandelson, and between September 2025 and February 2026 following the dismissal of Mandelson.
Roscoe has previously worked for His Majesty's Diplomatic Service in Iraq, Sierra Leone and the UK Mission to the UN.[3] Between 2006 and 2009, Roscoe was the chief press officer to prime ministers Tony Blair and Gordon Brown.[3] He served as communications secretary to Queen Elizabeth II from 2013 to 2016.[1] In 2017, he joined the Department for Exiting the European union as Communication Director and from 2019 to 2022 was the United Kingdom’s Ambassador to the General Assembly of the United Nations in New York.[3] Roscoe was appointed Deputy Head of Mission at the British Embassy in Washington D.C. in July 2022.[4]
In September 2025, Roscoe became chargé d'affaires ad interim to the United States for the second time following the dismissal of Peter Mandelson as ambassador by prime minister Keir Starmer, amid controversy surrounding Mandelson's association with the convicted sex offenders Jeffrey Epstein and Ghislaine Maxwell.[2] He previously served in that position in February 2025, between the departure of Karen Pierce and the appointment of Mandelson.
