WARSAW, Oct 25 : Poles began voting on Sunday in a general election expected to end eight years of centrist government, with surveys showing the eurosceptic conservatives firmly ahead after running a campaign of anti-refugee rhetoric and welfare promises. The opposition Law and Justice (PiS) party led by controversial ex-premier Jaroslaw Kaczynski commands an 8-to-12 point poll lead over the liberal, pro-European Civic Platform (PO) of Prime Minister Ewa Kopacz. Analysts say the PiS could even end up governing alone.     ?AFP
