Lower House of UK Parliament

The Parliament of the United Kingdom operates as a bicameral legislature, comprising two distinct houses, each with specific roles in the nation's governance. Understanding their structure is key to comprehending British democracy.

• The House of Commons is correctly identified as the lower house. It is the principal legislative body, composed of democratically elected Members of Parliament (MPs) who represent constituencies. The Commons holds supreme legislative authority, controls government spending, and is where the Prime Minister and most government ministers sit.
• The House of Lords is the upper house, consisting mainly of appointed life peers and hereditary peers. Its primary role is to scrutinize and revise legislation, but it possesses less power than the Commons.
• The term "Senate" refers to the upper house in many other countries, such as the USA, but not in the UK's parliamentary system.

Thus, the House of Commons is the foundational elected chamber.
