Sharjah24 - Reuters: Ukrainian President Volodymyr Zelenskiy said personnel changes were being carried out at senior and lower levels, following the most high-profile graft allegations since Russia's invasion that threaten to dampen western enthusiasm for the Kyiv government.

Reports of a fresh scandal in Ukraine, which has a long history of shaky governance, come as European countries bicker over giving Kyiv German-made Leopard 2 tanks - the workhorse of armies across Europe that Ukraine says it needs to break through Russian lines and recapture territory.

"There are already personnel decisions - some today, some tomorrow - regarding officials at various levels in ministries and other central government structures, as well as in the regions and in law enforcement," Zelenskiy said in his nightly video address on Monday.

Zelenskiy, who did not identify the officials to be replaced, said his plans included toughening oversight on travelling abroad for official assignments.

Several Ukrainian media outlets have reported that cabinet ministers and senior officials could be sacked imminently.
