Volodymyr Zelenskyy¡¯s surprise move to overhaul his government and potentially install an energy executive as prime minister is the latest sign of the Ukrainian president¡¯s determination to spare his war-weary nation a repeat of last winter¡¯s hardships.

Zelenskyy said Sunday on social media that he planned to replace Prime Minister Yuliia Svyrydenko as part of a broader change in ¡°political strategy,¡± a move that will trigger the resignation of the entire Cabinet under Ukrainian law.

She¡¯s likely to be replaced by either Sergii Koretskyi, chief executive officer of state-run energy company NJSC Naftogaz Ukrainy, or former Prime Minister Denys Shmyhal, according to people familiar with the matter. They declined to be identified because they¡¯re not authorized to discuss the matter publicly.
