Brussels, Jumada I 10, 1437, February 19, 2016, SPA -- EU leaders are struggling to strike a deal on reforms demanded by Britain, with different sides digging in their heels after a first round of summit negotiations, sources say, according to dpa. The talks yielded little progress on overcoming differences on the reforms, a British official said. EU President Donald Tusk was now expected to hold separate talks with British Prime Minister David Cameron and European Commission President Jean-Claude Juncker. Five points were still proving contentious, including the question of how long social benefits for EU citizens working in Britain may be restricted, diplomats said. --SPA 02:23 LOCAL TIME 23:23 GMT www.spa.gov.sa/w
