Parliament and the Executive

Parliament and Executive Icon
Parliament's role is not only to make laws but also to scrutinise and hold the Executive to account. The Executive (the Prime Minister, Cabinet, and government ministers) is drawn from Parliament, which creates a close relationship between the two. Parliament uses several mechanisms to check the power of the Executive, including backbenchers, select committees, the opposition, and question time.

The Role and Significance of Backbenchers

A backbencher is a Member of Parliament (in either House) who does not hold a government office or a front-bench opposition position. They sit on the "back benches" behind their party's front-bench team. Despite not being in government, backbenchers play a significant role in the legislative process and in holding the Executive to account.

Parliamentary Privilege

Parliamentary privilege is a set of constitutional rights and immunities that allow Members of Parliament to carry out their duties without interference from outside bodies, including the courts.

The Work of Select Committees

Select committees are one of the most important mechanisms through which Parliament scrutinises the work of the government. They are small, cross-party groups of MPs or Lords that investigate specific issues or oversee the work of government departments.

Summary: How Parliament Checks the Executive

Mechanism How It Works Strengths Limitations
Backbenchers Raise issues, introduce PMBs, rebel against the whip Can defeat the government; represent constituents directly Often constrained by party loyalty and the whip system
Select Committees Conduct inquiries, summon witnesses, publish reports Cross-party; specialist expertise; 30–40% of recommendations adopted Cannot compel attendance; recommendations not binding
The Opposition Shadow Cabinet scrutiny, Opposition Days, challenging legislation Organised, visible challenge; government-in-waiting Cannot outvote a large majority; motions are non-binding
Question Time / PMQs Ministers answer questions on a rota; PM faces PMQs weekly High-profile; forces public accountability; broadcast live Adversarial; evasive answers; limited time for depth
