Who has the oldest continuous parliament in the world?

The High Court of Tynwald is the parliament of the Isle of Man and has an unlimited, but not necessarily exclusive, legislative competence. Tynwald is of Norse origin and over 1,000 years old, and is thus the oldest parliament in the world with an unbroken existence.

It has two Branches, the Legislative Council and the House of Keys, which sit separately to consider legislation, but also sit together in Douglas, and annually at St John's, for other parliamentary purposes.

The Houses sit jointly, on Tynwald Day (normally on 5 July), at an open-air ceremony at Tynwald Hill at St John's. The Lieutenant Governor of the Isle of Man presides, unless HM The Queen as Lord of Mann, or a member of the Royal Family representing Her Majesty, is present. They also sit once a month in the Legislative Buildings in Douglas. Otherwise, the two Houses sit separately, with the House of Keys originating most legislation, and the Legislative Council acting as a revising chamber.
