What this dot point is asking
Edexcel wants you to explain the structure of the UK executive (the Prime Minister, the Cabinet, junior ministers and government departments), its main roles (proposing legislation, proposing a budget and making policy within the law), and its main powers, including the royal prerogative, the initiation of legislation and secondary legislation. This is examined through the 30-mark source and essay questions.
The structure of the executive
The Prime Minister appoints and dismisses ministers, chairs the Cabinet, sets the agenda, directs policy, represents the UK abroad and exercises many prerogative powers. The Cabinet is the formal decision-making body where collective policy is agreed and presented as the government's united position.
The roles of the executive
Edexcel lists the executive's main roles:
- Proposing legislation. The government sets out its programme (in the King's Speech) and introduces the bills that become most new law.
- Proposing a budget. The Chancellor proposes taxation and spending in the annual Budget.
- Making policy decisions within laws and budget. Ministers and departments make and implement policy across health, defence, education and the rest, within the framework set by statute and the Budget.
The powers of the executive
The royal prerogative is the most examined power because it lets the executive act without fresh parliamentary authority, though it is increasingly constrained by convention (a Commons vote before military action since the 2003 Iraq debate) and by the courts (the 2019 prorogation ruling).
Examples in context
- The royal prerogative on military action, now constrained by the convention of a Commons vote since 2003.
- Statutory instruments, the thousands of pieces of secondary legislation ministers make each year with light scrutiny.
- The King's Speech, the formal statement of the executive's legislative programme.
- The Budget, the executive's annual proposal on taxation and spending.

Edexcel 202020 marksExplain and analyse three powers of the UK executive. Edexcel 9-mark 'explain and analyse' style; develop each point.Show worked answer →
An "explain and analyse three" question is AO1 and AO2 only, no evaluation. Choose three distinct powers and develop each.
One: the royal prerogative, powers exercised by ministers in the Crown's name, including deploying the armed forces, making treaties and appointing ministers. Two: the initiation of legislation, where the executive controls most of the parliamentary timetable and proposes the bills that become most new law. Three: secondary (delegated) legislation, where ministers fill in the detail of Acts through statutory instruments without a full parliamentary process.
Markers reward three accurate, distinct powers, each developed with an example and a clear analytical link to executive dominance.
Edexcel 202220 marksEvaluate the view that the royal prerogative gives the UK executive excessive power. Reworded from a 30-mark essay to fit the schema; argue both sides and reach a judgement.Show worked answer →
A Section A 30-mark essay (shown as 20) on AO1, AO2 and AO3. Plan balanced arguments and a judgement.
Excessive: prerogative powers (deploying forces, treaties, appointments, prerogative of mercy) are exercised by the PM with little statutory check, allowing major decisions without parliamentary approval.
Not excessive: conventions now constrain the prerogative (a Commons vote before military action since 2003), the courts have limited it (the 2019 prorogation case), and Parliament can legislate to restrict it, so it is increasingly checked.
A Level 5 answer judges, for example, that the prerogative remains a significant concentration of power but is more constrained by convention and the courts than it once was, then sustains the line.
