Ukrainian President Volodymyr Zelenskiy urged his government on Thursday to keep a tight rein on spending in wartime, in a call that resulted in his culture minister, a proponent of several high-profile and costly projects, offering his resignation. "In a time of war like this the maximum amount of state attention and therefore state resources should go to defence," Zelenskiy said in his nightly video address, referring to a conversation he had earlier with Prime Minister Denys Shmyhal. And he asked Shmyhal to "consider replacing" Culture and Information Policy Minister Olexander Tkachenko.
