MINSK, Belarus — Ukraine’s embattled prime minister announced Sunday that he is resigning, opening the way for the formation of a new government to end a drawn-out political crisis.
In his weekly televised address, Arseniy Yatsenyuk said his resignation would be formally submitted to Parliament on Tuesday but his party would remain in the ruling coalition. The same day, Parliament is expected to elect the current speaker, Volodymyr Groysman, as the new prime minister.
Yatsenyuk’s Cabinet survived a no-confidence vote in February, but two parties left the governing coalition to protest the failure to oust the prime minister, who is under fire over the worsening economy and slow pace of reforms.
The withdrawal would deprive the ruling coalition of its majority in the Ukrainian Parliament.
If lawmakers had failed to form a new coalition and unite behind a new prime minister, that could have led to early elections, which President Petro Poroshenko had sought to avoid for fear of further destabilizing the situation in the country.
“Having done all I can for stability and continuity of the course, I announce the decision to hand off the obligations of the head of the Ukrainian government,’’ Yatsenyuk said.
‘‘From today I see my goals as broader than the powers of the head of the government,’’ Yatsenyuk said. He said he would focus on passing a new electoral law, enacting constitutional and judicial reform, and ensuring ‘‘the coalition’s control over the course of the new government.’’
Yatsenyuk said the two factions remaining in the coalition — one led by him and the other by Poroshenko — had won the support of a sufficient number of other Parliament members to restore their majority in the 450-seat Parliament. He said Poroshenko’s party has nominated Groysman as his replacement.
Political analyst Volodymyr Fesenko said it was now clear that Groysman would become prime minister, a step that should help to restore stability.
‘‘I am confident that Yatsenyuk consulted with the Western partners and was told that now the matter of political stability in Ukraine needs not games around the post of prime minister but a quick resolution of the political crisis,’’ Fesenko said.
Yatsenyuk became prime minister after Ukraine’s former Russia-friendly president was chased from power in February 2014 after massive street protests. Poroshenko was elected several months later with broad support and a seal of approval from Western leaders.
In recent months, political tensions have risen and some respected reformers have resigned, citing disenchantment with the government’s cronyism and entrenched corruption.
Ukraine has remained locked in a bitter tug-of-war with Moscow, which annexed the Crimean Peninsula in 2014 and supports a pro-Russian insurgency in eastern Ukraine, where fighting has killed more than 9,000 people since April 2014 and devastated the nation’s industrial heartland.
In February, former Prime Minister Yulia Tymoshenko announced that her faction was withdrawing from the governing coalition.
Yatsenyuk, an economist, is backed by the United States and other Western nations. He came to power two years ago amid the antigovernment protests in Maidan Square, which led to the downfall of President Viktor F. Yanukovych.
He was a popular figure at the start of his term, but his support declined because of a series of scandals and missteps. A political ally was forced to resign from Parliament after it emerged he was under investigation for money laundering in Switzerland.
In Ukraine’s Parliament, there are many procedural maneuvers that could keep Yatsenyuk in power. Earlier this year, Yatsenyuk faced a vote of no confidence, but the votes had been lined up in advance for him to stay in power, the Ukrainian media reported.
