The organisers said after the end of the demonstration that if the government does not resign by 25 September, they will announce pressure actions and will plan for another protest on 28 September.
"We demand the establishment of a temporary government of experts and the calling of early elections. If the government does not resign by 25 September, we will declare the right to resistance under the Constitution of the Czech Republic at a nationwide demonstration and announce coercive actions. We are already in talks with trade unions, businessmen, farmers, mayors, transport operators and other organisations to declare a strike," the organisers warned.
Shromáždění na Václavském náměstí probíhá v klidu a nemuseli jsme zatím řešit žádné vážnější problémy. Počet účastníků ve 14.30h odhadujeme asi na 70 tisíc. pic.twitter.com/9J4QGDEg3j
Among the speakers at Saturday's event were former Agrarian Chamber President Zdeněk Jandejsek and energy expert Vladimír Štěpán.
Other speakers included SPD MP Jiří Kobza, Trikolora chair Zuzana Majerová, Communist presidential candidate Josef Skála, economist and dean of the Faculty of Economics at the University of Economics in Prague Miroslav Ševčík, and lawyer Jana Zwyrtek Hamplová.
According to the organisers, the Czech Republic should declare neutrality, "free itself from direct political subservience to the EU, the WHO or the UN", secure cheap gas supplies from Russia and "free Czech industry from dependence on foreign companies".
