Sue Gray, Baroness Gray of Tottenham

Susan Ann Gray, Baroness Gray of Tottenham, CBE (born 1957) is a British special adviser and former civil servant who served as Downing Street Chief of Staff under Prime Minister Keir Starmer from July to October 2024, having previously served under Starmer as Chief of Staff to the Leader of the Opposition from 2023 to 2024.

She served from May 2021 to March 2023 as Second Permanent Secretary to the Cabinet Office, where she reported to the Chancellor of the Duchy of Lancaster. Her report into the Partygate scandal criticised the government led by Boris Johnson and contributed to his resignation as Prime Minister in September 2022 and ultimately to leaving Parliament in June 2023.

She resigned from the Civil Service in March 2023 to take up a job as Chief of Staff to the Leader of the Opposition, Keir Starmer. Her appointment provoked substantial controversy, and a Cabinet Office inquiry found that she had broken the Civil Service code. She was subject to scrutiny by the Advisory Committee on Business Appointments (Acoba), whose advice enabled her to work for the Labour Party from September 2023. When Starmer became Prime Minister following the 2024 General Election, Gray became his Downing Street Chief of Staff. Gray resigned after 4 months, citing the "intense commentary" around her position. Immediately after, her appointment as Envoy to the Prime Minister for the Nations and Regions was announced. In November 2024 it was confirmed Gray would not be assuming the role.
