The deputy prime minister of the United Kingdom is an honorific title^[1] given to a minister of the Crown and a member of the British Cabinet, normally to signify a very senior minister, the deputy party leader, or a key political ally of the prime minister. It does not entail any specific legal responsibilities, though the holder may be assigned some, and is usually paired with a departmental secretary of state position. The title is not always in use and prime ministers have been known to appoint informal deputies without the title of deputy prime minister. The current deputy prime minister is Angela Rayner.

The position of deputy prime minister carries no salary; the holder is appointed to another which draws a salary under the Ministerial and other Salaries Act 1975.^[2] The office is not always in use, and prime ministers may use other offices, such as First Secretary of State, to indicate the seniority. The holder of the position has no right to automatic succession.^[3]

Historically there has been resistance by the monarch to appointing an individual as deputy prime minister as it might be considered to infringe upon their royal prerogative to choose a prime minister.^[4] However, Rodney Brazier has more recently written that there is a strong constitutional case for every prime minister to appoint a deputy prime minister, to ensure an effective temporary transfer of power in most circumstances.^[5] Similarly, Vernon Bogdanor has said that that argument holds little weight in the modern context, since the monarch no longer has any real discretion, and that, even in the past, a person acting as deputy prime minister had no real advantage to being appointed prime minister by the monarch (though this might be different within political parties in relation to their respective leaderships).^[4] Like Brazier, he also says that there is a good constitutional case for recognising the office; for in the case of the death or incapacity of the incumbent prime minister.^[4]

Brazier has written that there are three reasons why a deputy prime minister has been appointed: to set out the line of succession to the premiership preferred by the prime minister, to promote the efficient discharge of government business and (in the case of Labour governments) to accord recognition to the status of the deputy leader of the Labour party.^[6]

When the position has been in use in the past, the deputy prime minister has deputised for the prime minister at Prime Minister's Questions.^[7]

Before World War II, while a minister was occasionally invited to deputise as prime minister when the prime minister was ill or abroad, no one was styled as such when the prime minister was in the country and physically able to run the government.^[8] This changed in 1942 when Clement Attlee was styled as deputy prime minister by Winston Churchill. This designation was seen as an exceptional result of a coalition and the war,^[9] and Attlee's 1942 appointment was not formally approved by the King^[10][11][12] and was a matter of form rather than fact.^[13] The designation was because Prime Minister Winston Churchill wanted to demonstrate the importance of the Labour party in the coalition, not for any reasons relating to succession; he actually left written advice that the King should send for Anthony Eden if he were to die, not Attlee.^[2] Unusually in comparison to other unofficial deputy prime ministers, Clement Attlee was described as deputy prime minister by Hansard, whereas other unofficial deputies are described using their official position.^[11]

After this, fearing a possible curtailment of the monarch's prerogative to choose a prime minister, no one was formally styled deputy prime minister (though there was often a senior minister generally regarded as such) until Michael Heseltine in 1995 was formally styled deputy prime minister. As the title of deputy prime minister did not hold any statutory authority Heseltine was also appointed as First Secretary of State.^[10] John Prescott served as deputy prime minister under Tony Blair during the entirety of Blair's premiership, and remains the longest serving deputy prime minister. Prescott's statutory authority was originally drawn from his concurrent position as Secretary of State for the Environment, Transport and the Regions, however in 2001 this department was broken up an Office of the Deputy Prime Minister (ODPM) was also formed within the Cabinet Office.^[11] To ensure he continued to hold statutory authority, he was appointed First Secretary of State. In June 2003, the ODPM became a separate department and absorbed the local government and regions portfolios from the defunct Department for Transport, Local Government and the Regions. During the 5 May 2006 reshuffle of Tony Blair's government, Prescott kept his position as deputy prime minister but lost his departmental authority and OPDM was renamed the Department for Communities and Local Government and headed by Ruth Kelly. The position was vacant during Gordon Brown's premiership.

After the Conservatives and the Liberal Democrats formed a coalition government in 2010, Nick Clegg was appointed deputy prime minister^[14][15] under David Cameron, and served in this role until he resigned after the Conservatives won a majority in the 2015 general election. During the coalition William Hague was appointed by Cameron as First Secretary of State, the only time that both these positions have existed concurrently but not been held by the same person. During this time Cameron described Hague rather than Clegg as being his "de facto political deputy".^[10] The office of deputy prime minister was vacant for the remainder of Cameron's premiership and the entirety of Theresa May's premiership.^[16]

In 2020, a year before being formally styled deputy prime minister, Dominic Raab deputised for Boris Johnson while Johnson was in hospital with COVID-19, though was not formally styled deputy prime minister until September 2021. Raab served as deputy prime minister during the remainder of Johnson's premiership. Thérèse Coffey served as deputy prime minister in September and October 2022 under Liz Truss, becoming the shortest serving deputy prime minister in history. After Rishi Sunak became prime minister, he reappointed Raab as deputy prime minister,^[17] making him the first non-consecutive holder of the office. Raab resigned in April 2023 after the investigation into his alleged bullying was published, and was succeeded by deputy prime minister Oliver Dowden, who resigned after the 2024 general election, whereupon he was replaced by Angela Rayner in Keir Starmer's Labour government.

There is no set of offices permanently ready to house the deputy prime minister.^[18] Deputy Prime Minister Nick Clegg maintained an office at the Cabinet Office headquarters, 70 Whitehall, which is linked to 10 Downing Street.^[19] Clegg's predecessor, Prescott, maintained his main office at 26 Whitehall.^[20]

The prime minister may also give them the use of a grace and favour country house.^[18] While in office, Nick Clegg resided at his private residence in Putney and he shared Chevening House with First Secretary William Hague as a weekend residence.^[21] Clegg's predecessor, John Prescott, used Dorneywood.^[18]

Nobody has the right of automatic succession to the prime ministership.^[22] However, it is generally considered that in the event of the death of the prime minister, it would be appropriate to appoint an interim prime minister, though there is some debate as to how to decide who this should be.^[23]

According to Brazier, there are no procedures within government to cope with the sudden death of the prime minister.^[24] There is also no such title as acting prime minister of the United Kingdom.^[25] Despite refusing "...to discuss a hypothetical situation" with BBC News in 2011,^[26] the Cabinet Office is reported to have said in 2006:^[27]

There is no single protocol setting out all of the possible implications. However, the general constitutional position is as set out below. There can be no automatic assumption about who The Queen would ask to act as caretaker Prime Minister in the event of the death of the Prime Minister. The decision is for her under the Royal Prerogative. However, there are some key guiding principles. The Queen would probably be looking for a very senior member of the Government (not necessarily a Commons Minister since this would be a short-term appointment). If there was a recognised deputy to the Prime Minister, used to acting on his behalf in his absences, this could be an important factor. Also important would be the question of who was likely to be in contention to take over long-term as Prime Minister. If the most senior member of the Government was him or herself a contender for the role of Prime Minister, it might be that The Queen would invite a slightly less senior non-contender. In these circumstances, her private secretary would probably take soundings, via the Cabinet Secretary, of members of the Cabinet, to ensure that The Queen invited someone who would be acceptable to the Cabinet to act as their chair during the caretaker period. Once the Party had elected a new leader, that person would, of course, be invited to take over as Prime Minister.

Additionally, when the prime minister is travelling, it is standard practice for a senior duty minister to be appointed who can attend to urgent business and meetings if required, though the prime minister remains in charge and updated throughout.^[28]

On 6 April 2020, when Prime Minister Boris Johnson was admitted into ICU, he asked First Secretary of State Dominic Raab "to deputise for him where necessary".^[29]

In addition to the many unofficial deputies (see below), some people have been formally appointed deputy prime minister. Ministers are appointed by the monarch, on the advice of the prime minister.^[30] Eight people can be described as definitely having been appointed deputy prime minister in such a manner.^{[Note 1][Note 2][31][32][12][13]}

The prime minister's second-in-command has variably served as deputy prime minister, first secretary and de facto deputy and at other times prime ministers have chosen not to select a permanent deputy at all, preferring ad hoc arrangements.^[9] It has also been suggested that the office of Lord President of the Council (which comes with leading precedence) has been intermittently used for deputies in the past.^[33][34]

Picking out definitive deputies to the prime minister has been described as a highly problematic task.^[35]

Bogdanor, in his 1995 publication The Monarchy and the Constitution, said that the following people had acted as deputy prime ministers (by this he meant they had chaired the Cabinet in the absence of the prime minister and chaired a number of key Cabinet Committees):^[36]

In an academic article first published in 2015, Jonathan Kirkup and Stephen Thornton used five criteria to identify deputies: gazetted or styled in Hansard as deputy prime minister; 'officially' designated deputy prime minister by the prime minister; widely recognised by their colleagues as deputy prime minister; second in the ministerial ranking; and chaired the Cabinet or took Prime Minister's Questions in the prime minister's absence.^[37] They said that the following people have the best claim to the position of deputy to the prime minister:^[35]

They also said that the following three people would have a reasonable claim:^[35]

Brazier has listed the following ministers as unambiguously deputy to or de facto deputies of the prime minister:^[38]
