Five opposition parties announced Tuesday they have requested a vote, expected to take place next week. Babis' centrist ANO (YES) movement is in a minority government with the leftist Social Democrats with support from the Communist Party.
Protesters have staged massive demonstrations demanding the resignation of Babis and his justice minister. Babis denies wrongdoing. Prosecutors are also looking into whether to indict Babis over alleged fraud involving EU funds in a separate case.
