Nearly five months after Moscow's invasion, Ukrainian President Volodymyr Zelenskyy suspended the country's security chief and top prosecutor, saying they failed to purge Russian spies from their organizations.

One of those sidelined in the biggest government overhaul of the war, SBU security service chief Ivan Bakanov, was a childhood friend of Zelenskyy.

Bakanov and Prosecutor General Iryna Venediktova embodied Zelenskyy's policy of putting young political allies in charge of fighting corruption following the former TV comic's 2019 election.
