The head of state aviation holding company Český Aeroholding has resigned from his post. Miroslav Dvořák’s departure as board chairman was announced in a press release on Wednesday. He has been under pressure from finance minister and ANO party boss Andrej Babiš to step down. The post will be filled by his former deputy, Václav Řehoř. The change must still be approved by Korean Air, which has a minority shareholding in Czech Airlines. Český Aeroholding’s main asset is its ownership of Prague’s main Václav Havel airport.
