A bid to force the Government into holding a referendum on the Lisbon Treaty was launched by the DUP's Nigel Dodds in Parliament yesterday.
The North Belfast MP was one of 20 MPs chosen in the ballot to put forward a Private Members' Bill in the Commons.
He is using the opportunity to push for a poll on the controversial treaty that created a president of Europe and insists the both the Conservatives and Labour have misled voters when they claim that can no longer done now it has been ratified.
Yesterday the Lisbon Treaty (Referendum) Bill, which “requires the holding of a referendum on the Treaty of Lisbon”, was laid before Parliament.
As well as winning support from DUP colleagues, the UUP's Lady Sylvia Hermon, Conservative, Labour and Liberal Democrat backbenchers have agreed to sponsor.
But the Bill is unlikely to get very far as the Parliamentary session will be cut short for the General Election and Mr Dodds' is half way down the list for consideration.
He said: “I am delighted to have received the backing of a wide spectrum of backbench opinion across all parties in the House of Commons for my Bill.
“It is vital that the people of the UK are allowed to have their say on the Lisbon Treaty which is in effect a new constitution for the EU. Both Labour and the Conservatives have let the people down on this issue.”
