The management of Poland's public television, radio and news agency PAP has been dismissed, according to the culture ministry, as one public news channel came off air.
Critics say that state-run media, in particular 24-hour news channel TVP Info, became an outlet for propaganda during the Law and Justice party's (PiS) eight years in government.
Prime Minister Donald Tusk's coalition has vowed to create new stations that take a more balanced approach.
Today, the signal of TVP Info disappeared and was replaced by that of the first channel of public television.
The same happened to its website.
"The end of TVPiS. TVP Info was turned off," Civic Platform - the biggest party in the new government - said on social media.
The culture ministry cited in its statement the need to restore impartiality of the outlets.
They were regularly accused of biased reporting, transmitting government propaganda and launching verbal attacks on the opposition.
Yesterday, Poland's parliament adopted a resolution calling on "all state authorities to immediately take action aimed at restoring constitutional order in terms of citizens' access to reliable information and the functioning of public media".
Media showed footage of PiS politicians at the headquarters of public television to "defend democracy", as party leader Jaroslaw Kaczynski told reporters.
"The illegal actions of the Minister of Culture in relation to TVP, Polish Radio and PAP show how the authorities that supposedly care about the rule of law violate it at every step," former PiS prime minister Mateusz Morawiecki wrote on social media.
"We will not give up. We will not allow for a dictatorship to be built in Poland".
The previous government was frequently criticised by the opposition and non-profit organisations for trying to stifle independent media and limit freedom of expression.
In 2020, global media watchdog Reporters Without Borders said that "partisan discourse and hate speech" were "the rule within [Poland's] state-owned media, which have been transformed into government propaganda mouthpieces".
