Political scientist warns KO and PiS: look what happened to Czech parties that once dominated

Professor Jarosław Flis from the Jagiellonian University warns that the dominance of KO and PiS in Polish politics may not last, citing the Czech example. The once-powerful duopoly of the centre-right ODS and the social-democratic ČSSD completely collapsed there, with both parties losing influence. Flis argues Polish parties should draw lessons from this.
