  • Parsifal SC, which conducts public opinion polls for the conservative news media enterprise Nova24TV, owned by members of right-wing SDS;
  • Research Center IJEK, which conducts the Pulse of Society public opinion polls and is the think tank of centre-right NSi;
  • Valicon, which conducts polls for Siol.net.
