The Westminster Parliament (Edexcel GCSE Citizenship Studies): Revision Note
Exam code: 1CS0
Executive, legislature, judiciary and monarchy
The role of the monarchy
The monarchy is the King, who is the head of state and carries out ceremonial duties with limited political power
The UK is a constitutional monarchy
King Charles III is the formal, symbolic leader of the country, while elected politicians run the government
Laws are made by Parliament in the monarch’s name, and the monarch carries out key constitutional roles
Example include opening Parliament, appointing the Prime Minister and giving Royal Assent to laws
The Monarch is neutral and carries out their role on the advice of the government, ensuring democracy is respected
The role of the legislature
The legislature is Parliament, which debates, makes and changes laws and checks the work of the government
Parliament is made up of the House of Commons and the House of Lords
It is where important national decisions are debated and made

The UK has a bicameral Parliament, which means it has two chambers
The House of Commons is made up of elected MPs who represent constituencies
The House of Lords is made up of unelected members who examine laws in detail
Parliament acts as the legislature, meaning it is the body that makes, debates and amends laws
For example, a new law about education or policing must be debated and approved by both Houses before it can become law
Parliament also has an important role in scrutinising the government
MPs question ministers, debate government policies and can vote against government proposals
The role of the Executive
The Executive is the part of government responsible for running the country on a day-to-day basis and makes decisions
It is made up of the Prime Minister, government ministers, senior civil servants, and political advisers
The Executive is responsible for developing government policy
For example, ministers decide plans for areas such as education, health or defence, which are then turned into laws by Parliament
The Executive is also responsible for putting laws and policies into action
Government departments, such as the Department of Health or the Home Office, are run by ministers and civil servants
The Executive plays a key role in crisis management
For example, during emergencies such as public health crises or national security threats, the Executive makes quick decisions to protect the public
Although powerful, the Executive is accountable to Parliament
Ministers must explain and justify their actions to MPs, helping to prevent misuse of power
The role of the judiciary
The judiciary is the system of courts and judges that interprets and applies the law and makes sure it is followed fairly
In the UK, the judiciary (judges and courts) is independent of the government
Judges are appointed based on experience and ability, not politics, and usually remain in post until retirement
This independence helps protect the rule of law and ensures fair decisions
The creation of the UK Supreme Court in 2009 strengthened judicial independence

The Supreme Court is separate from Parliament and government
It can make important judgements about whether the government has acted lawfully
The Supreme Court can decide whether new laws are compatible with the Human Rights Act 1998
If a law breaches human rights, the Court can issue a declaration of incompatibility
Parliament then decides whether to change the law
The Supreme Court also oversees devolution arrangements
It can rule on whether laws passed by the Scottish Parliament, Senedd or Northern Ireland Assembly go beyond their powers
The Court played a major role during the Brexit process
In 2017, it ruled that Parliament must approve triggering Brexit
In 2019, it ruled that the government’s suspension of Parliament was unlawful
Examiner Tips and Tricks
A common mistake is saying the monarch makes political decisions
In exam answers, be clear that real power sits with Parliament and the Executive
Credit is gained by explaining that the monarch acts on advice and follows convention, especially for roles like Royal Assent and appointing the Prime Minister
The House of Commons

The House of Commons is made up of 650 elected Members of Parliament (MPs)
MPs are elected by voters in constituencies across the UK
MPs usually work full time representing the interests of their constituents
The House of Commons is responsible for forming the government
The government is formed by the political party or parties that can command a majority in the House of Commons
The Prime Minister and most senior government ministers are normally members of the House of Commons
The House of Commons has the main law-making power in Parliament
The House of Commons determines the final outcome of most legislation
The House of Commons can reject or overturn changes suggested by the House of Lords
The House of Commons scrutinises the work of the government
MPs hold the government to account through debates, select committees and Prime Minister’s Questions
The House of Commons controls confidence in the government
A vote of no confidence in the government can lead to the government resigning or a general election
Parliamentary debate
Parliamentary debate is a formal discussion of issues, laws and policies in Parliament, where MPs and peers speak for or against proposals in the House of Commons and House of Lords
This debate allows ideas to be examined in detail
Different viewpoints and evidence can be considered before decisions are made
Debate helps to shape legislation
Bills can be challenged, improved and amended as a result of discussion
Parliamentary debate holds the government to account
Ministers must explain and defend their policies in public
Debate supports democracy
It ensures laws and policies are not rushed and reflect a range of opinions
The House of Lords

The House of Lords is made up of over 800 members
Members include life peers, crossbench peers, bishops of the Church of England and hereditary peers
The government has proposed removing hereditary peers from the House of Lords
Members of the House of Lords are not elected
Peers are appointed or inherit their position rather than being chosen by voters
Members are paid a daily allowance for attending the House of Lords
The House of Lords plays a key role in revising legislation
It debates proposed laws and suggests amendments to improve them
Members often use their specialist knowledge and experience during debates
The House of Lords scrutinises government decisions
It checks and examines legislation in detail before it becomes law
The powers of the House of Lords are limited
The House of Lords cannot interfere with financial bills such as the Budget
The House of Lords cannot block the House of Commons in the long term
