Poland's opposition demands no-confidence vote for government

  WARSAW, November 23 (Reuters): Poland's biggest opposition party, the centrist Civic Platform (PO), said on Friday it will submit to parliament a no-confidence motion in the government of the eurosceptic Law and Justice (PiS).   Slawomir Neumann, head of the PO parliamentary caucus, told a news conference the motion was in response to a corruption scandal involving the financial sector regulator and the way the government was dealing with it.   PiS holds a safe majority in the parliament, so the motion is seen mainly as a political gesture.
