The Gorilla protest in Nitra on Friday was attended by around 1,000 people, with speakers condemning corruption and oligarchy in Slovakia's political system, calling on thorough investigation into the Gorilla wiretapping scandal and postponing the general election from March to September. "The March election can't be fair. If any decent person joins this system, he must play according to the old rules. We need a certain period of time...," political activist Eduard Chmelar said.
