It is the prerogative of the monarch to summon and prorogue Parliament. Each parliamentary session begins with the monarch's summons. The new parliamentary session is marked by the State Opening of Parliament, during which the sovereign reads the Speech from the throne in the Chamber of the House of Lords, outlining the Government's legislative agenda.[18] Prorogation usually occurs about one year after a session begins, and formally concludes the session.[19] Dissolution ends a parliamentary term, and is followed by a general election for all seats in the House of Commons.
