Senior Civilian Representative in Afghanistan, to be the civilian counterpart to the
ISAF Commander, U.S. General
Stanley A. McChrystal and then U.S. General
David Petraeus. He was succeeded as ambassador temporarily by his predecessor, Cowper-Coles, and then by
William Patey, formerly
British Ambassador to Saudi Arabia.
In May 2011, Sedwill took over as the FCO's Director-General for Afghanistan and Pakistan (and thus as the UK's Special Representative for Afghanistan and Pakistan) from
Karen Pierce. He additionally became the FCO's Director-General, Political, in autumn 2012, replacing
Geoffrey Adams.
Sedwill said of his life before government "I've had a gun in my face from Saddam Hussein's bodyguards. A bomb under my seat at a polo match in the foothills of the Himalayas; I've been hosted by a man plotting to have me assassinated; I've been shot at, mortared and even had someone come after me with a suicide vest."
Home Office and National Security Adviser
In February 2013, Sedwill became the
Permanent Secretary at the Home Office, filling the vacancy left by
Helen Ghosh.
Sedwill replaced
Mark Lyall Grant as National Security Adviser in the Cabinet Office in April 2017.
During his time as Permanent Secretary, one of the organisations the Home Office is responsible for,
MI5, failed to adequately safeguard data. In 2019 Lord Justice Sir
Adrian Fulford stated MI5 had a "historical lack of compliance" with sections of the
Investigatory Powers Act in 2016.
Cabinet Secretary
Sedwill became acting Cabinet Secretary in June 2018, while
Jeremy Heywood took a leave of absence on medical grounds, and was appointed to replace Heywood on his retirement on 24 October 2018.
[Statement on Sir Jeremy Heywood](_blank)
gov.uk, 24 October 2018 He is the second Cabinet Secretary never to have worked at
HM Treasury, and the first whose career has been dominated by diplomatic and security work.
He was described as the Prime Minister's "first and only choice" to replace Heywood, with no recruitment process taking place and some suggesting the urgency of arrangements for the UK's departure from the European Union as a reason for the quick appointment.
Prime Minister
Theresa May was criticised for allowing Sedwill to remain as National Security Adviser alongside his role as Cabinet Secretary, with speculation that the role was being kept for Europe adviser
Oliver Robbins.
In a February 2019 interview Sedwill said he would retain his role as National Security Adviser to the Prime Minister since becoming Cabinet Secretary is part of moves to make a success of
Brexit
Brexit (, a portmanteau of "Britain" and "Exit") was the Withdrawal from the European Union, withdrawal of the United Kingdom (UK) from the European Union (EU).

In April 2019 it was reported that Sedwill had written to ministers on the

might have to stand down due to health issues. The article drew an angry response from Labour, which denounced the comments as a "scurrilous" attempt to undermine the party's efforts to gain power. Downing Street said that Sedwill would write to Corbyn after the party demanded an inquiry into alleged comments. Corbyn said the civil service has a duty to be non-political.
In November 2019, Sedwill blocked the publication of a document written by civil servants to cost the Labour Party's fiscal plans before a general election.
Shadow Chancellor John McDonnell had complained to Treasury Permanent Secretary
Tom Scholar in a meeting arguing it would interfere in the upcoming general election.
In June 2020, it was announced that Sedwill would be stepping down from his civil service appointments in September 2020. ''The Telegraph'' said that Downing Street regarded Sedwill as "too much of a Europhile and establishment figure" to be in post through planned Whitehall reforms.
Sedwill stepped down as national security adviser in September 2020. He was to be replaced by
David Frost, who was Johnson's
special adviser and chief negotiator in talks on the post-Brexit trade and security relationship with the EU. This would be a political appointment, while all previous national security advisers had been civil servants. However, an FOI answer stated that Frost continued as Chief Negotiator to the EU as of October 2020, and
David Quarrey took over the role of acting NSA.
Sedwill was replaced as Cabinet Secretary and
Head of the Home Civil Service by
Simon Case on 9 September 2020.
Later career
Sedwill was appointed a non-executive director of
BAE Systems plc on 1 November 2022. He is also a senior adviser and supervisory board member of
Rothschild & Co, the senior independent director and senior deputy chair of
