Helsinki (AFP) - Finns go to the polls on Sunday in legislative elections expected to oust the left-right government after a campaign that has focused heavily on how to lift Finland out of a three-year economic slump.Public opinion polls have predicted a resounding victory for the liberal-agrarian Centre Party leader Juha Sipila, a 53-year-old IT millionaire and newcomer to politics.Campaigning heavily on his business know-how, Sipila has vowed to get the economy back on track after three years of recession and stagnation, austerity and failed reforms."Our country deserves better," Sipila wrote on his blog on Saturday.
