Chapter Summary

The Prime Minister stands at the apex within British government. The occupant of the office leads the Cabinet and heads the party that usually enjoys a clear majority in the House of Commons. A strong Prime Minister may thus be in a position to achieve desired out-comes. However, the extent to which prime ministers achieve what they want varies. Prime ministerial power is variable and not a constant. Power may ‘zig zag’ from one premier to another (Blick and Jones 2010) as well as within a premiership.

The extent to which prime ministers can achieve their goals depends in part on who the Prime Minister is: what they want to achieve, and their skills in getting their way, will – as we have seen – vary from premier to premier. The political climate, not least the relationship between different political bodies, can change. A Prime Minister may enjoy a good parliamentary majority and be returned at the next election with a small and potentially difficult majority. Events at an international or national level may blow a government off course. Prime ministerial power thus varies not only from premier to premier but also within a premiership.

The variability of prime ministerial power is exacerbated by international developments, over which the Prime Minister may have little or no influence. The Prime Minister can be and frequently is powerful, but ultimately is dependent on what one Prime Minister, Harold Macmillan, allegedly summarised as ‘events, dear boy, events’.

Cabinet

the Cabinet consists of the leading members of the government, chosen by the Prime Minister. It is the place where major decisions are taken or ratified and where disagreements within government are resolved.

Cabinet Committees

Cabinet committees are appointed by the Prime Minister and are composed of Cabinet ministers (sometimes with junior ministers) to consider items of government business. Some are standing committees, some are ad hoc, to deal with specific problems or issues.

Cabinet Government

the view that collective government survives and that the Prime Minister is not the dominant force within government. Decisions are taken by a group of colleagues after discussions in Cabinet according to this view.

Collective Responsibility

all members of the government are collectively responsible for its decisions. Members, whatever their private reservations, must be prepared to defend government policy. If unable to do so, they must resign or be dismissed.

Core Executive

the group of people and institutions in Whitehall around the Cabinet and Prime Minister who decide most key policies. They include No. 10 staff, the Cabinet Office and senior civil servants, particularly those in the Treasury.

Governance

the act or manner of governing within or across territorial jurisdictions.

Prime Ministerial Government

the view most associated with Richard Crossman and John Mackintosh that the Prime Minister has become dominant, almost a President, and that the Cabinet has become part of the ‘dignified’ aspects of the system.
