Component 2.1 to 2.4: the structure and role of the Commons and Lords, their comparative powers, the legislative process, and how Parliament interacts with and scrutinises the executive.

What this dot point is asking

Edexcel wants you to explain the structure and role of the House of Commons and House of Lords, their comparative powers, the legislative process (including the Salisbury Convention), and how Parliament interacts with and scrutinises the executive through backbenchers, select committees, the opposition and question time. This is examined through the 30-mark source and essay questions in Section A.

The structure and role of the two Houses

The functions of Parliament are legislation (making law), representation (of constituents and the nation), scrutiny of the executive, the granting of consent to taxation and spending, and providing the personnel of government. Edexcel expects you to assess how well each function is fulfilled, not just to list them.

Comparative powers of the Commons and Lords

The debate over the relative power of the two Houses turns on the Lords' lack of democratic legitimacy: because it is unelected, it limits itself to revising and delaying, but its expertise and willingness to inflict defeats (it amends government bills frequently) make it a real check, especially on a government with a weak Commons position.

The legislative process

A bill normally passes through: first reading (formal introduction), second reading (debate on principle), committee stage (line-by-line scrutiny in a public bill committee), report stage (further amendment), third reading (final Commons vote), then the same stages in the other House, before royal assent. The Commons and Lords exchange amendments ("ping-pong") until they agree, with the Commons ultimately able to use the Parliament Acts to override the Lords.

Scrutiny of the executive

This is the most examined area, so hold the mechanisms and their limits.

• Select committees. Departmental committees (and the Liaison Committee, which questions the PM) investigate policy, take evidence and publish influential reports; backbench-led and increasingly independent, they are the strongest scrutiny tool.
• Backbenchers. Backbench MPs can rebel, table amendments, ask Urgent Questions and use the Backbench Business Committee; rebellions can defeat or reshape government policy, especially under a small majority.
• The opposition. The official opposition scrutinises, opposes and presents an alternative government, using Opposition Days and shadowing ministers.
• Question time. Prime Minister's Questions and departmental question times force ministers to account publicly, though PMQs is often more theatre than forensic scrutiny.

Examples in context

• The Liaison Committee questioning the Prime Minister, the apex of select-committee scrutiny.
• The Parliament Acts 1911 and 1949, which cap the Lords' delaying power and assert Commons primacy.
• Backbench rebellions during minority government (2017 to 2019), when Parliament repeatedly defeated the executive.
• The Salisbury Convention, the rule that keeps the unelected Lords deferring to the elected Commons on manifesto commitments.
