The Downing Street Chief of Staff, sometimes referred to as just The Chief of Staff, is one of the most high-ranking political appointes in HM Government, acting as a senior aide to the Prime Minister of Great Britain. The Holder of the position maintains a high level of executive authority within government and is the highest-ranking non-minister of state within the Cabinet of Great Britain.
The role of Chief of Staff was first set up as a principal and full executive role during the First Douglas Ministry to serve as a Deputy Prime Minister in all but name, owing to the lack of grandiose successors to the Prime Minister within his Government at the time. The role has only been officially held twice but various figures have been considered de-facto Chiefs of Staff and as such are listed here. Several Prime Ministers' also had a series of "Special Advisors", most notably the Viscount Sidmouth, with one advisor usually considered the Chief of Staff.
The first Downing Street Chief of Staff was William Scott-Chester. The office is currently held by Miann Somerset, The Earl of Lothian.

Footnotes
- ↑ William Somerset was never officially announced as Downing Street Chief of Staff but was internally considered as such. One of four Special Advisors during the Knightstone Premiership, Lord Douglas was the most senior of them during the First Knightstone Ministry and was a noted advisor of considerable influence. His informal retirement from politics during the timeframe of the Second Knightstone Ministry ends his tenure as de-facto Chief of Staff but he remained a Special Advisor to the Prime Minister throughout the entirety of The Baron Knightstone's time in 10 Downing Street.
