Greece's conservative government survived a no-confidence motion in parliament on March 28 over allegations it tried to manipulate the investigation into the deadly train crash that rocked the country last year.
The no-confidence motion was defeated, with 159 of the 300 MPs in parliament voting against and 141 voting in favour.
The conservative government of Prime Minister Kyriakos Mitsotakis has a parliamentary majority and was expected to reject the request brought by the socialist PASOK party on Tuesday.
The motion was brought after a newspaper publication alleged that a key audio recording from the night of the crash, which killed 57 people in February 2023, had been misleadingly edited.
Opposition parties accused the government of being behind the alleged ruse as part of an effort to bolster its preferred case that human error was to blame for the head-on collision.
"Public opinion has come to an irrevocable conclusion - that you are bent on a cover-up" of the train tragedy, Nikos Pappas, speaker of parliament from the main opposition Syriza party, told the chamber on Wednesday.
"You are called upon to give answers," he said.
Public opinion has reached an irrevocable conclusion - that you have aimed to cover up the train tragedy," said Nikos Pappas, speaker of the parliament from the main opposition Syriza party, on Wednesday.
"You are called upon to give answers," he said.
Opposition parties claim that the government has released the compiled tape to friendly media.
But Mitsotakis said publicly: "There was never a gag order. I'm looking you in the eye and telling you this."
Addressing what he previously called a "national trauma", Mitsotakis said "chronic state failures have met human error", insisting he wanted to tell the "truth" to a "distrustful and angry society". .
The disaster occurred when a freight and passenger train carrying 350 staff and passengers, mostly students, collided shortly before midnight near a tunnel outside the central city of Larissa.
A year after the incident, relatives of the victims claim that, despite the government's promises of a full investigation, state authorities wasted time and missed important evidence.
Experts appointed by the relatives' families said the crash site had been cleared of debris and topsoil before investigators could fully examine it.
The body of a young woman traveling on the passenger train is still missing.
The families' experts also say the freight train was carrying undeclared chemicals that caused a huge explosion after the crash, killing people who would otherwise have survived.
Critics pointed to Mitsotakis' address to the nation just hours after the incident, in which he said "everything" pointed to human error.
Government spokesman Pavlos Marinakis called the To Vima report "baseless".
The main opposition Syriza party called on Mitsotakis, who was easily re-elected in June, to resign.
Opposition parties were already furious last week after a four-month parliamentary inquiry into the incident ended without blaming senior politicians.
More than 30 railway employees and officials have been charged in connection with the February 28, 2023 crash, with a trial expected to begin in June.
For decades, Greece's 2,552 km railway network has been plagued by poor management, poor maintenance and outdated equipment.
Last year, the government got rid of another vote of no confidence because of a wiretapping scandal involving state intelligence and the prime minister's office./BGNES
