Ukrainian President Volodymyr Zelensky has put forward a fresh head of government as part of a ministerial overhaul.
Zelensky told MPs the change will aid the country deal with pressing issues.
During a meeting with outgoing Premier Denys Shmyhal, Zelensky reviewed ways to protect the nation’s energy grids.
He also called in the CEO of state-run gas giant Naftogaz to settle sector shortfalls.
Top aides admit swift action is vital after a sudden hold-up on Patriot missiles and after Trump’s remarks on a similar deal sparked talk.
Officials insist prompt steps are required to keep air defences and energy hubs running.
