Legislation: Parliament is the engine of law-making, where bills are proposed, debated, and refined. While the government initiates most legislation, Parliament ensures these proposals are thoroughly examined before they become law.
Scrutiny: One of the most vital roles is checking the work of the government. This is achieved through parliamentary questions, debates, and the work of Select Committees, which investigate government policy and spending.
Representation: MPs represent the interests and concerns of their specific geographical constituencies. In a representative democracy, citizens delegate decision-making power to these elected officials who act on their behalf in the national legislature.
Parliamentary Sovereignty: This is the defining principle of the UK constitution, stating that Parliament is the supreme legal authority. It has the power to create or end any law and cannot be overriden by the courts or previous parliaments.
Representative Democracy: The UK system relies on the idea that the people exercise their power by electing representatives. These representatives are expected to use their judgment and conscience to make decisions that benefit the nation and their constituents.
Executive Accountability: Because the government is drawn from Parliament, it must constantly justify its actions to the legislature. If a government loses the confidence of the House of Commons, it is traditionally expected to resign or call an election.

Distinguish Roles: Always clearly distinguish between the 'Government' and 'Parliament' in your answers. A common mistake is using these terms interchangeably; remember that Parliament includes the opposition and backbenchers who challenge the government.
Focus on Primacy: When discussing the relationship between the two houses, emphasize why the Commons is supreme. Its democratic mandate is the source of its constitutional authority over the unelected Lords.
Identify Scrutiny Mechanisms: Be prepared to explain how scrutiny happens. Mentioning specific tools like Select Committees or Prime Minister's Questions (PMQs) demonstrates a deeper understanding of parliamentary procedure.
