Cabinet of the United Kingdom in the context of "India Office"

The prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet, and selects its ministers. Modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, so they are invariably members of Parliament.

The office of prime minister is not established by any statute or constitutional document, but exists only by long-established convention, whereby the monarch appoints as prime minister the person most likely to command the confidence of the House of Commons. In practice, this is the leader of the political party that holds the largest number of seats in the Commons. The prime minister is ex officio also First Lord of the Treasury (an office often associated with the premiership between 1721 and 1895, after 1902 always united to it, and, after 1905, an official title of the position), Minister for the Civil Service, the minister responsible for national security, and Minister for the Union. The prime minister's official residence and office is 10 Downing Street in London.

His Majesty's Government, abbreviated to HM Government or otherwise UK Government, is the central executive authority of the United Kingdom of Great Britain and Northern Ireland. The government is led by the prime minister (Keir Starmer since 5 July 2024) who selects all the other ministers. The government is currently supported by the Labour party, which has had a majority in the House of Commons since 2024. The prime minister and his most senior ministers belong to the supreme decision-making committee, known as the Cabinet.

Ministers of the Crown are responsible to the House in which they sit; they make statements in that House and take questions from members of that House. For most senior ministers this is usually the elected House of Commons rather than the House of Lords. The government is dependent on Parliament to make primary legislation, and general elections are held at least once every five years to elect a new House of Commons, unless the prime minister advises the monarch to dissolve Parliament, in which case an election may be held sooner. After an election, the monarch selects as prime minister the leader of the party most likely to command the confidence of the House of Commons, usually by possessing a majority of MPs.

The Privy Council, formally His Majesty's Most Honourable Privy Council, is a formal body of advisers to the sovereign of the United Kingdom. Its members, known as privy counsellors, are mainly senior politicians who are current or former members of either the House of Commons or the House of Lords.

The Privy Council formally advises the sovereign on the exercise of the royal prerogative. The King-in-Council issues executive instruments known as Orders in Council. The Privy Council also holds the delegated authority to issue Orders of Council, mostly used to regulate certain public institutions. It advises the sovereign on the issuing of royal charters, which are used to grant special status to incorporated bodies, and city or borough status to local authorities. Otherwise, the Privy Council's powers have now been largely reserved to its executive committee, the Cabinet of the United Kingdom, which serves as the senior decision-making body of the government. The council is administratively headed by the Lord President of the Council who is a member of the cabinet, and appointed on the advice of the Prime Minister.

His Majesty's Attorney General for England and Wales (Welsh: Twrnai Cyffredinol Lloegr a Chymru) is the chief legal adviser to the Sovereign and Government in affairs pertaining to England and Wales as well as the highest ranking amongst the Law officers of the Crown. The Attorney general is the leader of the Attorney General's Office and currently attends (but is not a member of) the Cabinet. Unlike in other countries employing the Common law legal system, the attorney general does not govern the Administration of justice; that function is carried out by the Secretary of State for Justice and Lord Chancellor. The incumbent is also concurrently the Advocate General for Northern Ireland.

The position of Attorney General dates back to at least 1243, when records indicate that a professional attorney was appointed to represent the King's interests in court. The position first took on a political role in 1461 when the holder of the office was summoned to the House of Lords to advise the Government there on legal matters. In 1673, the attorney general officially became the Crown's adviser and representative in legal matters, although still specialising in litigation rather than advice. The beginning of the 20th century saw a shift away from litigation and more towards legal advice. Today, prosecutions are carried out by the Crown Prosecution Service (CPS) and most legal advice to government departments is provided by the Government Legal Department, both under the supervision of the attorney general.

The lord chancellor, formally titled Lord High Chancellor of Great Britain, is a senior minister of the Crown within the Government of the United Kingdom. The lord chancellor is the minister of justice for England and Wales and the highest-ranking Great Officer of State in Scotland and England, nominally outranking the prime minister. The lord chancellor is appointed and dismissed by the sovereign on the advice of the prime minister. Prior to the union of England and Scotland into the Kingdom of Great Britain, there were separate lord chancellors for the Kingdom of England (including Wales) and the Kingdom of Scotland. Likewise, the Lordship of Ireland and its successor states (the Kingdom of Ireland and United Kingdom of Great Britain and Ireland) maintained the office of lord chancellor of Ireland until the establishment of the Irish Free State in 1922, whereupon the office was abolished.

The lord chancellor is a member of the Cabinet and is, by law, the minister of the Crown responsible for the efficient functioning and independence of the courts. The lord chancellor thus leads the Ministry of Justice and is the judiciary's voice within Cabinet. In 2005, there were a number of changes to the legal system and to the office of the lord chancellor. Previously, the lord chancellor was also the presiding officer of the House of Lords, the head of the judiciary of England and Wales and the presiding judge of the Chancery Division of the High Court of Justice. The Constitutional Reform Act 2005 transferred these roles to the lord speaker, the lord chief justice and the chancellor of the High Court respectively.

The royal prerogative is a body of customary authority, privilege, and immunity attached to the British monarch (or "sovereign"), recognised in the United Kingdom. The monarch is regarded internally as the absolute authority, or "sole prerogative", and the source of many of the executive powers of the British government.

Prerogative powers were formerly exercised by the monarch acting on their own initiative. Since the 19th century, by convention, the advice of the prime minister or the cabinet—who are then accountable to Parliament for the decision—has been required in order for the prerogative to be exercised. The monarch remains constitutionally empowered to exercise the royal prerogative against the advice of the prime minister or the cabinet, but in practice would likely only do so in emergencies or where existing precedent does not adequately apply to the circumstances in question.
