In a vote on 20 February, 525 MEPs voted in favour of the EU's 'Reform Treaty' and 115, mainly from the far left and the far right, voted against it.
Protests were voiced mainly by British and Danish eurosceptics, who claim the treaty is essentially a reworked version of the rejected Constitution and that it should be put to a referendum.
"The truth is that you are too chicken to have a referendum," Nigel Farage, a British member of Parliament's Independence/Democracy Group told treaty supporters, accusing them of resorting to "totalitarian means" to get the text through. "What the EP is engaged in here in today's debate is nothing less than a massive exercise of deceit," he commented.
Thus far, Ireland remains the only EU member set to hold a referendum on the Lisbon Treaty, and Farage expressed his hope that Irish citizens would give a "large resounding 'no'" to the text.
The vote is expected to be held in May or June and Ireland's European Affairs Minister Dick Roche has admitted that securing a 'yes' vote may prove to be a "big challenge". "We can't be complacent," he said, adding that an Irish rejection of the treaty would "park Europe in a eurosceptic cul-de-sac".
Meanwhile, treaty ratification could be delayed in Germany, meaning that the EU's largest country would not sign off the treaty in time for it to come into force at the beginning of 2009 as planned. According to a report in German daily Die Welt, politicians from the Left Party, as well as Peter Gauweiler, a centre-right politician from one of governing parties - the CSU - are examining the text to see if they can bring a case before the country's constitutional court.
German MPs are widely expected to approve the treaty when it comes before parliament in May. However, the text then needs to be signed off by the country's president, Horst Köhler.
If this does happen, Köhler would have to decide whether to go ahead and sign off the treaty anyway or rather wait for the court to make its case, meaning ratification would be delayed.
