LONDON, Jumada II 29, 1436, Apr 18, 2015, SPA -- Britain's opposition Labour Party has slipped slightly further behind the ruling Conservatives ahead of next month's general election, according to an opinion poll to be published in Sunday's Observer newspaper, Reuters reported. The poll showed support for the Conservatives steady at 36 percent, while support for Labour dropped by 2 percentage points since the last poll a week ago to 32 percent, market research company Opinium said on Saturday. With less than three weeks to go before the May 7 election, most opinion polls have shown voters fairly evenly split between Britain's two main political parties, but neither are likely to win enough seats to hold a clear parliamentary majority. -- SPA 22:09 LOCAL TIME 19:09 GMT www.spa.gov.sa/w
