Britain's opposition Conservatives are set for a landslide victory in national elections due within a year, the People newspaper said on Sunday, after the party extended an opinion poll lead. The People's poll, conducted by YouGov, showed 40 percent support for the Conservatives, up 2 percentage points from a YouGov poll earlier in the week, while Prime Minister Gordon Brown's Labor Party was down 1 percentage point to 24 percent. Support for the center-left Liberal Democrats was also down 1 percentage point to 17 percent. The People said this put the Conservatives on track to win 378 seats at the next elections, versus 199 seats for Labor and 42 for the Liberal Democrats, giving them a 137-seat majority.
