Aug. 14 (Bloomberg) -- Polish Prime Minister Jaroslaw Kaczynski said early elections are ``the only solution'' to the country's political crisis after he fired ministers from the government's two junior parties, ending the 15-month-old coalition.

Elections should take place in November ``at the latest,'' Kaczynski told public radio today. A bitter dispute between the Law & Justice party, founded by Kaczynski and his brother Lech, the Polish president, and its partners Self Defense and the Polish Families' League led to the dismissal yesterday of all four ministers from the two smaller parties.

Relations deteriorated after Kaczynski fired Self Defense Chairman Andrzej Lepper from the cabinet last month amid a bribery probe by a state anti-corruption body. Lepper denies wrongdoing and both smaller parties have demanded an inquiry into the agency's activities, a request the premier has rejected.

The date of elections is currently in the hands of the opposition Democratic Left Alliance, which has said it may not support an early poll unless two parliamentary investigations are set up. Dissolving parliament, the quickest way of triggering early elections, needs a two-thirds majority in the 460-seat chamber. Law & Justice and the largest opposition party, Citizens' Platform, would need the Alliance's 55 votes to gain enough support for this.

Police Raid

The Alliance is seeking a probe into the operations of the anti-corruption agency that led to Lepper's dismissal. It also wants an investigation into the circumstances surrounding the death of Barbara Blida, a former Alliance lawmaker, who shot herself during a police raid in April.

Elections can also be held if the prime minister offers to resign and the president and parliament cannot establish a stable government after making three attempts.

A record 62 percent of Poles are dissatisfied with Kaczynski's work, an Aug. 3-6 survey of 859 potential voters for the Warsaw-based Center for Public Research showed, an increase of 4 percentage points from a month ago.

``The coalition was worth forming,'' the prime minister said in today's interview. ``Firstly, there was no other option at the time, and secondly, we've succeeded in doing a lot.''
