Frequently Asked Questions (FAQ)

Royal Prerogative powers are executive powers historically exercised by the Sovereign, now mostly exercised by Prime Ministers and Cabinet Ministers without requiring Parliamentary statutory approval (such as declaring war, negotiating international treaties, issuing passports, and granting honors).

The Sovereign acts as Head of State in a Constitutional Monarchy. Before any bill passed by Parliament becomes an enforceable Act of Law, it must receive Royal Assent from the Sovereign.
