Brussels, 13/09/2007 (Agence Europe) - British Liberal Democrats, the third largest political force in the United Kingdom and currently in the opposition, support Labour Prime Minister Gordon Brown in his intention not to organise a referendum on the future amending EU treaty, which could be adopted in Lisbon on 19 October. However, should pressure in favour of a referendum become too great (as the Conservatives, a small part of the Labour party and the eurosceptical media continue to call for it), British citizens would have to be invited to give their views on two specific alternatives: - adoption of the treaty or the country's withdrawal from the European Union. Sir Menzies Campbell, who leads the British Liberal Democrats, was of the view that a referendum is not necessary for adopting the text of the treaty. However, he said, if there were to be a referendum, then it should be a more fundamental referendum on whether or not the UK should remain in the European Union. Last weekend, on the fringe of the informal meeting of EU foreign ministers in Viana do Castelo, British Minister David Miliband had pointed out that London did not intend to adopt the new treaty by referendum, but simply by parliamentary vote (EUROPE 9498).
