Jonathan Powell, former chief of staff to Tony Blair, has been named as the new national security adviser by Prime Minister Keir Starmer.
Powell, a veteran diplomat, previously led UK discussions on the Chagos Islands’ sovereignty and was a pivotal figure in the Northern Ireland peace process.
Powell will succeed Tim Barrow, who has held the role since 2022, and will be based at No 10.
His responsibilities will include advising on the UK’s stance on the Ukraine conflict and navigating the international repercussions of Donald Trump’s presidency.
This appointment follows Starmer’s decision to cancel former Prime Minister Rishi Sunak’s choice of Gen Gwyn Jenkins for the position, leading to a re-run of the selection process.
Originally, Barrow was set to take on the role of US ambassador, but this appointment has now been suspended, with Karen Pierce staying on as the current ambassador amid Trump’s transitional phase in the US.
Powell’s appointment marks the Prime Minister’s move to secure an experienced and loyal former diplomat in the role.
A known Blairite, Powell was among the top advisers who remained in government throughout Blair’s decade in office. Currently, he serves as chief executive of Inter Mediate, a UK charity focused on conflict resolution.
Following his appointment, Starmer praised Powell’s extensive background, stating, “Jonathan has devoted his career to protecting the interests of the country, with 17 years in the Foreign Office and 10 years as chief of staff in No 10.
His work in negotiating the Belfast [Good Friday] Agreement and experience with global conflicts make him uniquely qualified to guide the government in facing future challenges.”
Powell expressed his gratitude, acknowledging the interconnected nature of national security, international relations, and domestic policies.
“As the Prime Minister has highlighted, national security is central to this country’s response to our many challenges, and an integrated approach will be essential to our success,” he said.
Powell looks forward to working closely with ministers and officials in his new role.
