Ukrainian President Volodymyr Zelensky has announced a fresh head of government as part of a ministerial overhaul.
He told parliament the transition will aid the country deal with pressing issues.
During a meeting with outgoing Premier Denys Shmyhal, Zelensky reviewed ways to strengthen the nation’s energy grids.
He also called in the head of state-run gas giant the energy company to settle sector obstacles.
Top aides admit rapid action is vital after a sudden hold-up on Patriot missiles and after the ex-president’s remarks on a similar deal sparked talk.
Officials insist rapid steps are required to keep air defences and energy hubs running.
