PRAGUE (AP) — The Czech prime minister says that his government will resign over unexplained business dealings of the country's finance minister and rival.

Premier Bohuslav Sobotka says that he will meet President Milos Zeman this week to formally submit the government's resignation.

Tuesday's move reflects tensions in the ruling coalition about six months before the parliamentary election.

Sobotka says that there are suspicions that Finance Minister Andrej Babis avoided paying taxes in the past that he didn't explain properly.

Babis, the country's second-richest businessman, heads a centrist movement that is a favorite to win October's ballot, paving the way for him to become prime minister.

Sobotka's Social Democrats are a distant second.
