Northern Ireland Assembly wants the UK to hold a referendum on the Lisbon Treaty.
The Northern Ireland Assembly motion of 20th October 2009, passed by 47 to 19 votes, indicated: “That this Assembly notes the verdict of the Republic of Ireland electorate on the Lisbon Treaty referendum; reaffirms its support for a referendum in the United Kingdom on the Treaty; and calls for a declaration from those parties aspiring to form the incoming Government of the United Kingdom to give an unequivocal commitment to hold, within a twelve month period from assuming office in 2010, a binding referendum on the Lisbon Treaty that is unconditional and unrelated to how other member states choose to vote, and the result of which will not be held in abeyance pending a further referendum on the subject.”
