London, Sha'aban 8, 1436 AH, May 26, 2015, SPA -- British Prime Minister David Cameron and European Commission President Jean-Claude Juncker has begun renegotiating the terms of Britain's EU membership ahead of an in-out referendum, dpa reported. Cameron hosted a dinner for Juncker at Chequers, the prime minister's official residence in southern England, officials said. The prime minister, whose Conservative party won a parliamentary majority in national elections earlier this month, has promised to renegotiate the terms of Britain's EU membership and hold an in-outreferendum before the end of 2017. Cameron is to travel to several European capitals this week, including Paris and Berlin, to push his case for reform. He is expected to give more details to his plans for the referendum in a speech to the state opening of parliament on Wednesday. Changes to welfare payments designed to cut the number of EU migrants will be an "absolute requirement" in the negotiations with other EU nations, Cameron said in a speech last week. -- SPA 11:45 LOCAL TIME 08:45 GMT www.spa.gov.sa/w
