Ukrainian President Volodymyr Zelensky has announced a fresh new leader 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 gas firm to settle sector problems.
Top aides admit urgent action is vital after a snap hold-up on Patriot missiles and after Trump’s remarks on a similar deal sparked talk.
Officials insist urgent steps are required to keep defence networks and the grid running.
