The island's parliament, Tynwald, is claimed to have been in continuous existence since 979 or earlier, purportedly making it the oldest continuously governing body in the world, though evidence supports a much later date. Tynwald is a bicameral or tricameral legislature, comprising the House of Keys (directly elected by universal suffrage with a voting age of 16 years) and the Legislative Council (consisting of indirectly elected and ex-officio members). These two bodies also meet together in joint session as Tynwald Court.
