Italian Prime Minister Romano Prodi has called for a vote of confidence on his center-left government after 20 months in power.
Mr. Prodi, whose coalition ranges from communists to centrist Catholics and Greens, announced the move Tuesday.
The vote - set for Wednesday - was initiated after former Justice Minister Clemente Mastela, who stepped down last week, said his small centrist party would oppose Mr. Prodi in a confidence vote. Mastela is the target of a government corruption probe.
The confidence vote was announced today in the Chamber of Deputies, where Mr. Prodi's coalition has a clear majority. A vote is also to be held in the upper Senate chamber, where he no longer has a majority. The timing of that vote has not been announced.
If the prime minister loses either vote, he will have to resign.
