DAVOS, Switzerland, Rabi'II 11, 1437, Jan 21, 2016, SPA -- European leaders said they will do what they can to make sure British Prime Minister David Cameron can support his country's continued future in the European Union in a referendum expected this year, AP reported. Mark Rutte, the Dutch Prime minister whose country currently holds the rotating presidency of the 28-country EU, said Thursday he's "fairly optimistic" a deal with Britain will emerge in February, but that he's "not absolutely sure." Addressing a panel at the World Economic Forum at the Swiss ski resort of Davos, Rutte voiced his strong support for Britain's continued membership of the EU as the country is outward-looking and trade-oriented. Cameron is seeking a series of reforms on things like benefits, powers for national parliaments and movement of people. He has voiced his hope that a successful renegotiation will lead to the British people backing Britain's future in the referendum that is expected this year. French Prime Minister Manuel Valls said it would be a "tragedy" if Britain left the EU so-called Brexit. --SPA 14:24 LOCAL TIME 11:24 GMT www.spa.gov.sa/w
