AustraliaAustraliaGovernment & politics
AustraliaAustralia
Australia combines a Westminster parliamentary system with a US-style elected Senate and a written federal constitution. The monarch is head of state, represented by the Governor-General, but power rests with the Prime Minister and Cabinet, drawn from the elected House of Representatives. Unusually, the Senate is powerful and fully elected, and the High Court can strike down laws that breach the constitution. Voting is compulsory.
United Kingdom
The UK is a constitutional monarchy with an uncodified constitution. The monarch is the head of state but reigns rather than rules — the role is symbolic and politically neutral. Real power lies with the Prime Minister, who is the leader of the party commanding a majority in the elected House of Commons, and the Cabinet. Parliament is sovereign, meaning it can make or unmake any law, and there is no single written constitution or supreme court that can strike laws down on constitutional grounds in the American sense.
