Le Pen has been a vocal critic of the European Reform Treaty (formally known as the Treaty of Lisbon) which was signed by EU member states on 13 December 2007, and entered into force on 1 December 2009. In October 2007, Le Pen suggested that he would personally visit Ireland to assist the "No" campaign but finally changed his mind, fearing that his presence would be used against the supporters of the NO vote. Ireland finally refused to ratify the treaty. Ireland is the only EU country which had a citizen referendum. All other EU states, including France, ratified the treaty by parliamentary vote, despite a previous citizen referendum where over 55% of French voters rejected the European Reform Treaty (although that vote was on a different draft of the Treaty in the form of the Constitutional Treaty). After the Irish "No" vote, Le Pen addressed the French President Nicolas Sarkozy in the European Parliament, accusing him of furthering the agenda of a "cabal of international finance and free market fanatics." Ireland has since accepted the treaty in a second Lisbon referendum.
