On March 26, a group called the Citizens' Forum presented a petition bearing more than 56,000 signatures — far more than the 40,000 needed for consideration — to the Dutch parliament demanding a referendum addressing the Netherlands' participation in efforts at political integration among EU countries. After a parliamentary commission confirms the validity of the signatures, the lower chamber of parliament has to decide whether a referendum should be held or not. Euroskeptics Citizens' Forum, a group of about a dozen citizens, most of them in academia, launched their campaign in the weeks after British Prime Minister David Cameron announced in January that he would organize a referendum after elections in 2015 on the United Kingdom's relationship with the European Union.
