Ukrainian Prime Minister Arseniy Yatsenyuk announced his resignation Thursday in an address before parliament after the tenuous coalition that kept him in power finally splintered.
"I am announcing my resignation in connection with the collapse of the coalition and the blocking of government initiatives," Yatsenyuk said.
Parliament has struggled to approve budget laws, part of a legislative logjam that Yatsenyuk said jeopardized military funding in the war-torn nation of 45 million people.
Yatsenyuk, 40, came to power in February after a revolution that forced from power pro-Russian president Viktor Yanukovych, who drew ire for efforts to slow assimilation with the Europe Union. But in recent days the nationalist Svoboda party and the UDAR movement led by famed former boxer Vladimir Klitscho split from the coalition that helped make Yasenyuk prime minister.
Parliament speaker Oleksandr Turchynov said it was up to Udar and Svoboda to propose a candidate for temporary prime minister. Several media outlets, including the Kyiv Post, reported that Deputy Prime Minister Volodymyr Groysman, 36, will serve in the role.
Balazs Jarabik, visiting scholar at the Carnegie Endowment for International Peace, said the resignation was expected -- and necessary so a new elections can be held. A new government could strengthen President Petro Poroshenko, he said.
"#Poroshenko concentrates all power in his hand: controls acting gov (Groysman), his party leads in polls ahead of early elections. #Ukraine" Jarabik tweeted.
The country has been in turmoil since November, when Yanukovych backed off an agreement to extend Ukraine's EU ties. The agreement had not been well received by Russia or Ukraine's nation's ethnic-Russian minority that dominates eastern Ukraine.
But Yanukovych's decision to instead strengthen ties with Russia drew massive and sometimes violent protests in pro-European Kiev. Yanukovych fled to Russia and a legislative coalition gave Yatsenyuk the prime minister's job, further aggravating relations with ethnic Russians in eastern Ukraine as well as Russia itself.
Separatists in Crimea, encouraged by Russia, declared their independence and backed it with an overwhelming referendum victory in March. Meanwhile, the European Union and Ukraine signed a political and economic agreement, committing Ukraine to a deal Yanukovych had rejected in favor of better ties to Moscow.
The deal, along with a sympathetic government in Moscow, further heated ethnic-Russian dissent in other parts of eastern Ukraine. The country has been dogged by military conflict as more regions in the east seek to break away.
