Ukraine's parliament elects new PM

Ukraine's parliament on Thursday approved the appointment of Naftogaz state energy boss Sergiy Koretsky as the new prime minister, part of a disputed government reshuffle ordered by President Volodymyr Zelensky, AFP reported.

Koretsky, 48, is seen by Zelensky as a manager who can lead the country through another tough winter set to be marked by relentless Russian strikes on the energy system.

But the Ukrainian leader has not fully explained the reasons for the shake-up of Ukraine's top political team, which triggered an outcry on Thursday over the ousting of the popular defence minister.

"We weathered the harshest winter and ensured an uninterrupted supply of gas to Ukrainians, despite significant losses of our own production," Koretsky said in a parliamentary speech, hailing his achievements as head of Naftogaz.

"We have proven that government administration can and should be effective," he added.

Koretsky led Naftogaz, the backbone of Ukraine's heating system, through last winter, when Russian drones and missiles sparked mass blackouts and heating outages during freezing temperatures.

Yulia Svyrydenko resigned as prime minister on Tuesday as part of the reshuffle, for which Zelensky offered only the vague explanation that Kyiv was "changing its political strategy" amid "new challenges and new tasks".
