Government ministers

Most ministers are members of the House of Commons, although the government is also fully represented by ministers in the House of Lords.

The composition of governments can vary both in the number of ministers and in the titles of some offices. New ministerial offices may be created, others may be abolished, and functions may be transferred from one minister to another.

The Prime Minister

As head of the UK government, the Prime Minister oversees the operation of the Civil Service and government agencies, appoints members of the Cabinet, and is the principal government figure in the House of Commons. The Prime Minister is also, by tradition, the First Lord of the Treasury – and draws his or her salary in that role, rather than as Prime Minister.

The Prime Minister's unique position of authority comes from majority support in the House of Commons and the power to appoint and dismiss ministers. By modern convention, the Prime Minister always sits in the Commons.

The Prime Minister presides over the Cabinet, is responsible for allocating functions among ministers and, at regular meetings with the Queen, informs her of the general business of the government.

The Prime Minister's other responsibilities include recommending a number of appointments to the Queen. These include high-ranking members of the Church of England, senior judges and certain civil appointments. He also recommends appointments to several public boards and institutions, as well as to various royal and statutory commissions.

The Prime Minister's Office supports him in his role as head of government. This includes providing policy advice, tracking the delivery of government commitments and initiatives, and ensuring effective communications to Parliament, the media and the public.

The Cabinet

The Cabinet is the committee at the centre of the British political system and the supreme decision-making body in government.

The British Prime Minister has traditionally been referred to as ‘primus inter pares’, which means ‘first among equals’ and demonstrates that he or she is a member of the collective decision-making body of the Cabinet, rather than an individual who has powers in their own right. The Prime Minister is first among equals simply in recognition of the responsibility held for appointing and dismissing all the other Cabinet members.

Cabinet ministers are the highest-ranking ministers in the government, and most government departments have one Cabinet minister (or more). Most Cabinet ministers are titled ‘Secretary of State’ – although some have traditional titles, such as the Chancellor of the Exchequer and the Chief Whip.

How Cabinet works

Every Tuesday while Parliament is in session, the Cabinet meets in the Cabinet room at 10 Downing Street to discuss the issues of the day. Government Cabinets have met in the same room since 1856, when it was called the Council Chamber.

The Prime Minister chairs the meeting and sets its agenda; he also decides who speaks around the Cabinet table, and sums up at the end of each item. It is this summing up that then becomes government policy.

Cabinet committees

In addition to the whole Cabinet meetings, a range of Cabinet committees meet in smaller groups to consider policy with other ministers who are closely involved with the relevant issue.

The Prime Minister decides who will sit on these committees, and the relevant committee is consulted for clearance before any new piece of legislation that an individual minister wants to introduce is brought before Parliament.

A list of the current committees and the ministers who sit on them is available from the Cabinet Office website.
