LONDON, Sha'ban 20, 1436, Jun 7, 2015, SPA -- More than 50 lawmakers from David Cameron's Conservative Party are to join a campaign backing Britain's exit from the European Union unless the British prime minister achieves radical changes in the bloc, according to the Sunday Telegraph newspaper, Reuters reported. The lawmakers will be part of a new group called Conservatives for Britain (CfB), which will support Cameron's bid for reform while urging an end to EU membership unless significant changes are achieved, the paper said. -- SPA 01:31 LOCAL TIME 22:31 GMT www.spa.gov.sa/w
