OTTAWA, Sept. 23 (Xinhua) -- The Liberal Party is inching up in public support while the Conservatives still hold a sizable lead during the last few days, according to a new poll about Canada's upcoming election.

    A Canadian Press Harris-Decima poll taken over the last four nights put the Conservatives at 37 percent support, a two-point drop over the last few days, while the Liberals climbed to 24 percent, a one-point increase over Monday's figures.

    The survey has the New Democrats and Bloc Quebecois steady at 17 percent and eight percent respectively, while the Green party is down one point at 11 percent.

    The Liberals' support has been sliding since the election campaign started on Sept. 7, widening its gap with the Conservatives to as much as 10 percentage points.

    "In the national numbers, I think we can say that the deterioration for the Liberals has stopped. They may have hit a floor," said Harris-Decima president Bruce Anderson.

    The Conservatives were once put at 41 or 42 percent, raising the hopes that they may get a majority government.

    The new poll surveys 300 people a night in a rolling national sampling and the figures are based on interviews with 1,232 people Friday through Monday.

    The results are considered accurate to within plus or minus 2.8percentage points, 19 times in 20.
