UKRAINIAN President Volodymyr Zelensky has sacked his country’s prosecutor general and the head of the intelligence services amid allegations of collusion with Russia. 

He issued executive orders late on Sunday firing SBU chief Ivan Bakanov and prosecutor general Iryna Venediktova, citing more than 650 cases of high treason. 

Mr Zelensky claimed that there was evidence that more than 60 officials had been spying for Moscow in Russian-controlled areas of Ukraine.
