Ukraine’s parliament approved Denys Shmygal as the new prime minister on Wednesday after his predecessor resigned following a leak of a recording where he criticised President Volodymyr Zelensky.

Analysts say Zelensky was unhappy with the government’s handling of the economy and its flagging popularity, sparking a reshuffle of his top team—the foreign, defence and finance ministries all getting new bosses.

Most lawmakers voted to back deputy PM Shmygal, Zelensky’s nominee who previously served as a regional governor and earlier worked for an energy company owned by the country’s richest man Rinat Akhmetov.

Former prime minister Oleksiy Goncharuk quit on Tuesday—the second time he had offered to resign after a leaked recording emerged in January of him questioning Zelensky’s grasp of economics.

Zelensky was disappointed in Goncharuk and the work of the government as a whole, Kiev-based political analyst Volodymyr Fesenko told AFP.

“The last straw was the growing discontent” among the population, he said.

Shmygal promised to address economic and social issues in a country still locked in a conflict with separatists in the east, saying: “Ukrainians must see and feel that the state is protecting them.”

Parliament also approved other cabinet members, including Dmytro Kuleba as foreign minister, Andriy Taran as defence minister and Igor Umansky as finance minister.

Comedian-turned-politician Zelensky came to power last April promising to “break the system” that had ruled Ukraine since independence in 1991.

His campaign pledges included ending the conflict in the east, fighting corruption and reforming an economy still reliant on foreign aid.

But some international investors questioned the timing of the reshuffle—with the coronavirus outbreak causing market uncertainty.

Also, Ukraine and the International Monetary Fund (IMF) agreed a new $5.5 billion programme in December, but IMF officials have not yet approved the deal.
