Slovakia's Prime Minister Robert Fico offered on Wednesday to resign under pressure from the opposition for his handling of a scandal over the killing of a journalist investigating political corruption.
"Today I have offered my resignation to the president of the republic" Andrej Kiska, Mr Fico said in a public address.
"If the president accepts it, I am ready to resign tomorrow."
Mr Fico, 53, has been struggling since February with a scandal over the killing of journalist Jan Kuciak and his fiancee.
The killing had sparked protests against Mr Fico's government, with tens of thousands of Slovaks turning out for rallies.
The prime minister's three-party coalition government was facing a no-confidence vote by politicians scheduled for next Monday.
Interior minister Robert Kalinak had already resigned two days ago in a bid to save the government from collapsing.
But a minor member of Slovakia's three-way governing coalition, the Most-Hid party, raised the pressure further, calling for early elections.
Mr Kiska had also called for early elections - or sweeping government changes - earlier this month.

Mr Fico has resisted the call for snap polls. He warned the country could "plunge into chaos if the current opposition takes power".
Slovakian daily Sme reported Mr Fico's Smer-SD party may field deputy prime minister Peter Pellegrini, 42, as a candidate to succeed Mr Fico.
Kuciak and fiancee Martina Kusnirova, both 27, were found shot dead on 25 February at their home near the capital Bratislava.
Police said Kuciak's death was "most likely" related to his investigation on ties between Slovakia's top politicians and Italy's 'Ndrangheta mafia.
The murder and Kuciak's article, published after his death, sparked a wave of anti-government sentiment in Slovakia, an EU and NATO member of 5.4 million people.
Mr Fico's close aide Maria Troskova was alleged to have links to one of the Italians named in Kuciak's story.
The EU urged Slovakia to swiftly investigate the murder.
"The top priority for all of us must be to carry out an independent and thorough investigation of the facts and bring those responsible to justice," the EU's security commissioner, Julian King, told MEPs in Strasbourg on Wednesday.
"We call upon the Slovak authorities to do this quickly."
The killing of Kuciak and Kusnirova raised fresh concern about media freedom and corruption both in Slovakia and Europe.
It followed the assassination in October of investigative journalist Daphne Caruana Galizia who had denounced corruption in Malta.
