When people hear “United Kingdom,” they often think the King or Queen runs the country—but in AP Comparative Government, the UK is the key case for understanding how a democracy can work without a single written constitution and why real power comes from Parliament, political parties, and the Prime Minister.

In this video, you’ll learn:

• The UK basics: England, Scotland, Wales, and Northern Ireland

• What it means to have an uncodified constitution (rules come from laws, courts, and conventions)

• Head of State vs Head of Government (Monarch vs Prime Minister)

• How Parliament works: House of Commons (elected, most powerful) vs House of Lords (unelected review)

• The idea of parliamentary sovereignty and why Parliament matters so much

• Fusion of powers: why the executive comes from the legislature and why the PM needs a Commons majority

• UK elections: First Past the Post (FPTP) and single-member districts—and how that shapes parties

• Why parties matter: Conservatives, Labour, Liberal Democrats, plus regional parties

• Devolution and why regional governments reshape power inside the UK

• Rule of law and the role of courts (including a UK Supreme Court)
