Ukrainian Prime Minister Arseniy Yatsenyuk announced Sunday that he would resign, amid an ongoing political crisis.
“We cannot let the government be destabilized when the country is at war,” he said during a televised address.
His formal resignation is expected Tuesday.
Yatsenyuk called for the formation of a new government, and said on Twitter that politician Volodymyr Groysman had been nominated to replace him as Prime Minister.
He also said that the heart of Ukraine’s problems is not “purely political,” but ethical.
“As of today my goals are broader: new electoral law, Constitutional reform, Judicial reform, Ukraine’s membership in the EU and NATO,” Yatsenyuk wrote in a tweet.
Political division has deepened in Kiev over the past few months. In February, Ukrainian President Petro Poroshenko had called for Yatsenyuk to step down.
