A referendum was expected to take place in the United Kingdom in 2006 to decide whether the country should ratify the proposed Treaty establishing a Constitution for Europe. However, following the rejection of the Constitution by similar referendums in France in May 2005 and the Netherlands in June 2005, the UK vote was postponed indefinitely. The question was thought to have been settled when the constitution was superseded by the Treaty of Lisbon, which Parliament ratified in 2008 without holding a referendum.
