How are the two legislatures similar in structure?

Both Congress and Parliament are bicameral, both have a chamber based on population-based single-member districts, and in both a bill must pass both chambers before becoming law.

Compare the terms served by members of each elected chamber.

Members of the House of Representatives serve two years and senators six, while members of the House of Commons serve until the next general election, which must be held within five years.

What is the fundamental difference between the two second chambers?

The Senate is wholly elected and is the more powerful of the two American chambers, whereas the House of Lords is wholly unelected and is subordinate to the Commons.

How is the House of Lords composed?

The House of Lords consists of life peers appointed on the nomination of party leaders and the House of Lords Appointments Commission, and 26 senior Church of England bishops. The last hereditary peers were removed in April 2026.

On what basis is the Senate composed?

The Senate gives every state two senators regardless of population, elected directly by that state's voters since the Seventeenth Amendment of 1913.
