Origins
Since 1989, Britain has had more years with a Deputy Prime Minister than without. What is this position? What do they do? And why did it come into being?
For much of the history of the British Premiership, the Office of Deputy Prime Minister did not exist. It was only during the Second World War that Clement Attlee was ‘styled’ Deputy Prime Minister, taking over much of Churchill’s domestic work and allowing him to concentrate on the war.
Clement Attlee:
‘I acted for Churchill on the fairly numerous occasions when he was absent from the country at various conferences. This gave me valuable experience for the future. It fell to me not infrequently to have to announce bad news to the House of Commons.’ (Attlee, p. 176).
Once the war was over, George VI was keen that normal constitutional procedure reassert. When Winston Churchill suggested that Eden become Deputy Prime Minister in 1951, George VI responded that the office ‘does not exist in the British constitutional hierarchy’.
During Prime Ministerial history, particularly during the 18th and 19th Centuries, there was a natural alliance between the Leader of the House of Lords and the Leader of the House of Commons, with one the Prime Minister and the other, effectively, the deputy. One example of this is Lord Derby and Benjamin Disraeli as a political double act during the 1850s and 1860s. Until 1911, the two Houses had equal legislative power, and the Lords had not been formally subordinated to the Commons. Government required skilled leadership in both, and it was perfectly acceptable for a peer to serve as Prime Minister. Though the Deputy Prime Minister position did not exist, a frequent leader and deputy relationship at the top of politics certainly did.
Moreover, for much of the post-war era, Deputy Prime Minister was more of a de facto position than de jure. Willie Whitelaw (1979-88), Michael Stewart (1968-70), ‘Rab’ Butler (1957-63), and Herbert Morrison (1945-51), were all understood by colleagues to be the PM’s deputy. But they were never referred to as Deputy Prime Minister in Hansard or really understood as having that particular title.
In some ways, the development of the title of Deputy Prime Minister resembles that of the development of the Prime Minister’s title itself, which, for the first two centuries of the office’s existence, was not ‘known to law’. It is only in more modern times, during the tenure of Geoffrey Howe (1989-90), Michael Heseltine (1995-97), John Prescott (1997-2007), Nick Clegg (2010-15), Dominic Raab (2021-22, 2022-23), Thérèse Coffey (2022), and Oliver Dowden (2023-), that the position has become a formal title.
