Britain"s Labour Party has slashed the main opposition Conservative Party"s opinion poll lead to six points, giving the government its best showing in almost a year as voter confidence in the economy recovers, Reuters reported. The Ipsos MORI survey in Sunday"s Observer newspaper showed Prime Minister Gordon Brown"s Labour Party on 31 percent, the centre-right Conservatives on 37 percent and the Liberal Democrats on 17 percent. Labour"s recovery points to the narrowest gap between the two main parties in any survey since last December, and would result in a hung parliament if replicated in a parliamentary election -- the first since 1974. A gap of five points would likely see Labour win more seats than the Conservatives at the next election, which must be held by June, the paper quoted the pollsters as saying.
