Brussels, 12/05/2014 (Agence Europe) - Over the weekend, UK Conservative Prime Minister David Cameron reaffirmed that he would not continue as prime minister - whatever the result of the 2016 general elections - if he failed to organise a referendum on the EU in 2017, British media report. This condition of a referendum will be a red line for the discussions on a future grand coalition, Cameron added. He is currently in coalition with the Liberal Democrat pro-Europeans. Cameron also said he was confident that he could renegotiate London's relationship with Brussels, and that his party was currently the only one, as the European elections approach, to have “a plan to change Europe”, enabling the British to have their say. Cameron nevertheless said that he did not want to put an end to the free movement of intra-European migrants, despite the “concerns” that the arrival of over 30,000 Romanians and Bulgarians in the UK as of 1 January raises. However, he continues to support the idea of hardening the conditions for receiving social benefits. The change that he greatly wants to obtain is a clause that London would not be forced into an “ever closer Union” - a clause that he intends to call for should there be victory on the referendum, as he had previously announced on 16 March in a seven-point EU reform plan.
