KIEV, July 24 – Prime Minister Arseniy Yatseniuk resigned on Thursday, following Parliament's failure to pass legislation to take control over an increasingly precarious energy situation and to increase army financing.

Earlier on Thursday, two parties quit the government coalition, forcing new elections to a parliament whose make-up has not changed since before the toppling of pro-Russian President Viktor Yanukovych in February.

His successor, President Petro Poroshenko, supported the move, which one politician said would clear "Moscow agents" from the chamber.

Yatseniuk's resignation could leave a hole at the heart of decision-making as Ukraine struggles to fund a war with pro-Russian rebels in its east and deals with the aftermath of a plane crash that killed 298 people.

The usually mild-mannered Yatseniuk bellowed at politicians who had failed to pass a law to allow a liberalization of control over Ukraine's pipeline system.

He said politicians risked losing the hearts and minds of Ukrainians who had protested for months in the "Maidan" demonstrations in favor of joining Europe and against Yanukovych.

"History will not forgive us," he told parliament, Reuters reported."Millions of people made this revolution. We did not take the European choice but the 'heavenly hundred' and thousands of other Ukrainians did," he said, referring to those killed, mainly by sniper fire, during the protests.

Yatseniuk, who has been central to talks with the European Union and the United States, cannot leave office immediately, political analysts said, because he is obliged to continue his duties before a new prime minister and government are installed.

But his impassioned speech underlined the frustration of many in Ukraine that change in the higher echelons of power was taking too much time.

Morale has also sunk in Kiev since the downing of a Malaysian airliner in rebel-held territory in eastern Ukraine last week, even though Ukrainian forces are making headway in the military campaign against the separatists.
Poroshenko welcomed the decision by the nationalist party Svoboda and the Udar party of former boxing champion Vitaliy Klitschko to withdraw from the majority coalition in parliament.
