Czech Prime Minister Bohuslav Sobotka announced Tuesday he would submit his resignation -- which also entails that of his cabinet -- after a row with his billionaire finance minister, whose business activities have caused a storm.

"I will shortly present my resignation to President Milos Zeman. It is unacceptable for Andrej Babis to stay on as finance minister," said Sobotka, in an announcement six months before an October election.
