The Ukrainian government on Tuesday confirmed the resignation of multiple high ranking officials amid large-scale corruption allegations, in what's being called the biggest mass resignation and graft scandal since the Russian invasion began.

Some dozen officials have quit their posts after a huge political shake-up over allegations and probes into cases ranging from bribery, to mismanagement of aid funds for purchasing food, to embezzlement, to driving expensive cars while common people suffer under wartime conditions.

A top presidential adviser and four deputy ministers - among these two defense officials, along with five regional governors were forced out of their posts. And among the regional governors to step down included officials overseeing regions which have seen intense fighting, including the Zaporizhzhia and Kherson regions, where Russian forces have lately reported gains.
