KIEV, April 13 - Ukraine's two largest pro-Western political parties have reportedly reached agreement on a new pro-EU government that will be headed by parliament speaker Volodymyr Hroysman, an ally of President Petro Poroshenko.

Dmitry Solyarchuk, Hroysman’s press secretary, announced the coalition deal on his Twitter account late on April 13.

Horysman and his government would replace the cabinet of Prime Minister Arseniy Yatseniuk, who resigned on April 10 amid a corruption scandal and troubles stemming from the government's battle against Russia-backed separatists in the east of the country.

Yatsenyuk’s party, the pro-Western People’s Front, has been in tense coalition talks with the president’s party, the Petro Poroshenko Bloc, since April 10 in order to come to agreement on the structure and personnel in the new cabinet.

Several members of Ukraine’s parliament also confirmed that a coalition agreement had been reached after days of debate and negotiations.

They said the deal included an agreement on who should head all of Ukraine's ministries except the Health Ministry.

Parliamentary deputy Maksim Bourbak said the new prime minister and his ministers would be formally announced on April 14.

Squabbling over top jobs in Ukraine's government delayed a parliament vote on a Cabinet reshuffle on Tuesday.

Lawmakers said the new Cabinet would not include U.S.-born Natalia Jaresko, who led the finance ministry and whose reforms were considered crucial for disbursement of the International Monetary Fund’s loans.

Her departure could be a disappointment for some of Ukraine's Western allies, who have praised her stewardship of the country's finances amid economic meltdown and a separatist conflict.

The finance minister post is especially sensitive given the cash-strapped country's strategic dealings with the International Monetary Fund and other foreign lenders.

Oleksandr Danyliuk has been chosen to take over from her if Hroysman is approved by parliament as prime minister, according to several lawmakers.

Danylyuk, 40, is the deputy head of Poroshenko's administration and his appointment to head the finance ministry would increase the president's grip on policymaking - something that will upset some of the reformists. (rfe/ez)
