TL;DR
Péter Magyar will be sworn in as Hungary's new prime minister after his Tisza party won a landslide victory, ending Viktor Orbán's 16-year rule. The Tisza party now holds 141 seats in parliament, while Orbán's Fidesz party has dropped to 52 seats.
Hungary's new prime minister, Péter Magyar, is set to be sworn in, almost a month after he steered his Tisza party to a landslide victory, sweeping away 16 years of rule by Viktor Orbán.
Tisza holds 141 seats out of 199 in the new parliament - up from zero, a result of the party being founded just two years ago.
A big "celebration of freedom and democracy" is planned on Saturday in front of parliament in Budapest, along the shores of the Danube. Magyar has told Hungarians to step through the "gateway of regime change".
Orbán's Fidesz party crumbled from 135 to 52 seats, and shows signs of imploding.
He and other key party figures have decided not to take their seats in parliament, and their political future is uncertain, beyond a vague commitment to "rebuild the national side".
Each day brings new revelations or allegations of corruption against a party which has governed Hungary almost unchallenged since 2010. Magyar has promised a "change of system" as well as a change of government.
It is not known whether Orbán will attend Saturday's opening session of parliament, even as a simple guest.
"The main priority is to set up the government... on the ruins of the previous one," Zoltán Tarr, incoming Minister for Social Relations and Culture, told the BBC.
"We are ready to face a very grim economic situation. But at the moment, we just don't know the severity."
A spending spree initiated by the Orbán government in the past eight months came on top of years in which state contracts and funds were channelled to business circles close to Fidesz.
The budget deficit has already swollen close to the planned target for the whole year.
The incoming government is at pains to show that it is morally stronger than Fidesz.
One prominent businessman, György Wáberer, who switched from Fidesz to Tisza a week before the election, told a journalist he had donated £242,000 (€280,000, $331,000) to Tisza.
Magyar promptly returned the money to him.
When Magyar's brother-in-law, Márton Melléthei-Barna, was named justice minister, the new government was bitterly criticised on social media.
On Thursday evening, Melléthei-Barna announced that he was withdrawing his candidacy for the post, "to ensure that not even the slightest shadow is cast on the transition".
Incoming Tisza ministers say there will be no revenge against the outgoing government, but those guilty of financial crimes will be held accountable. A new "office to recover stolen assets" will be set up.
"I don't think that we should talk about a guillotine," said Tarr, in response to calls for those responsible for siphoning off the national wealth to go on trial.
