Downing Street Chief of Staff
The office of Downing Street Chief of Staff is the most senior political appointee in the Office of the Prime Minister of the United Kingdom, acting as a senior aide to the prime minister, a powerful, non-ministerial position within Her Majesty's Government. The role of chief of staff initially had executive authority, and at the time of its creation, was referred to as "almost certainly the most powerful unelected official in the country", and possibly "the third most powerful altogether" after the prime minister and the chancellor of the exchequer. Since 2007 the  role does not legally have executive authority, although the post holder remains by definition the senior adviser to the prime minister. From 1997 to 2019 and from November 2020, the title of chief of staff has been held by the most senior special adviser at Downing Street. Steve Barclay, the Member of Parliament for North East Cambridgeshire, has served as chief of staff since February 2022 following the resignation of Dan Rosenfield. He is the first MP to do so. Description. The chief of staff is an appointed special advisor or a career civil servant who is personally and politically  close to the prime minister. The responsibilities of the post have varied according to the wishes of the sitting prime minister. Since the chief of staff is at the centre of the Downing Street operation, he or she will always be influential and closely involved in government policy formulation and implementation, political strategy and communication, and generally advising the prime minister. History. The first official chief of staff in 10 Downing Street was David Wolfson, under Margaret Thatcher from 1979 to 1985. The position of Downing Street Chief of Staff was recreated by Tony Blair upon his becoming prime minister  in 1997 and Jonathan Powell held the post for ten years. In 1997 Tony Blair gave his chief of staff, a special advisor, 'unprecedented powers' to issue orders to civil servants. Previously the Cabinet secretary had been the most senior non-ministerial figure in the British Government, and along with the principal private secretary to the prime minister had supported the prime minister in the running of 10 Downing Street. Following the creation of the role, the chief of staff supplanted the principal private secretary in running Downing Street operations and effectively replaced the power of the Cabinet secretary in  terms of co-ordinating government policy. Although the Cabinet secretary continued to be a highly important role, through remaining responsible for making sure that the civil service was organised effectively and was capable of delivering the Government's objectives, the chief of staff replaced the Cabinet Secretary as the "right-hand man" for the prime minister. "Powell had been at the epicentre of power. As Tony Blair's chief of staff, he was the ultimate fixer, the prime minister's first line of defence against events, baby-catcher in chief. When things went wrong, people called Powell." When Powell stood  down as chief of staff at the end of the Blair premiership in June 2007, the incoming prime minister, Gordon Brown, temporarily appointed civil servant Tom Scholar as both Downing Street chief of staff and principal private secretary to the prime minister. This was changed upon Scholar's scheduled departure in January 2008, when the title chief of staff was divided amongst two posts in an attempt to split the political policy communication role from the management of civil servants within Number 10. As such, senior civil servant Jeremy Heywood replaced Scholar as principal private secretary to the prime minister , a position he had held under Tony Blair several years earlier, with the role of chief of strategy and principal advisor to the prime minister (effectively chief of staff) being given to political advisor Stephen Carter. After less than a year in the post Carter resigned, becoming a minister and receiving a peerage amid speculation that his part of the chief of staff role had insufficient authority to direct cross-government operations. Heywood continued as both principal private secretary and Downing Street Chief of Staff for the remainder of the Brown Premiership. Upon David Cameron becoming prime minister in May  2010, Heywood returned to the civil service, enabling him to be appointed as the first Downing Street Permanent Secretary. He was replaced as Downing Street chief of staff by Conservative advisor Edward Llewellyn. Cameron also created the role of Downing Street deputy chief of staff, with responsibility for supporting the chief of staff, which was given to Catherine Fall. Theresa May appointed two joint chiefs of staff in Nick Timothy and Fiona Hill upon becoming prime minister in 2016. Former minister Gavin Barwell succeeded Timothy and Hill after the 2017 general election. The formal title was out of use between  July 2019 and November 2020, under prime minister Boris Johnson, when the role was overseen by Dominic Cummings as chief adviser and Edward Lister as chief strategic adviser. However, during this time, Cummings was noted to be the "de facto" chief of staff. When Cummings departed Downing Street, Johnson appointed Lister as acting chief of staff. Lister was succeeded Dan Rosenfield. He was succeeded by Steve Barclay in February 2022 after his resignation.
