VILNIUS, Lithuania (AP) — Lithuania Prime Minister Gintautas Paluckas stepped down on Thursday following investigations into his business dealings that prompted protests in the Baltic country’s capital calling for his resignation.

Lithuanian President Gitanas Nausėda announced Paluckas’ resignation to the media on Thursday morning. A spokesperson for Paluckas did not immediately respond to a request for comment.

Paluckas, a newly established leader of the center-left Social Democrats, ascended to the role late last year after a three-party coalition formed following parliamentary elections in October. His entire cabinet is now expected also to resign, potentially leaving the country without an effective government weeks before Russia holds joint military exercises with neighboring Belarus.

Paluckas has recently been dogged by media investigations into his business and financial dealings. Several media outlets published investigations in July regarding Paluckas’ past and present ventures and alleged mishandlings, including ones more than a decade ago. The Baltic country’s anti-corruption and law enforcement agencies subsequently launched their own probes.

In a devastating blow to his reputation, the media also revealed that Paluckas never paid a significant part of a 16,500 euro fine ($19,039) in connection with a 2012 criminal case dubbed the “rat poison scandal.”

Paluckas was convicted of mishandling the bidding process for Vilnius’ rat extermination services while serving as the capital city’s municipality administration director. Judges for the country’s top court in 2012 ruled that he abused his official position by illegally granting privileges to the company that offered the highest price in the bid.

He was also sentenced to two years behind bars, but the sentence was suspended for one year and he ultimately was never imprisoned.

The Social Democratic party leader denied any wrongdoing regarding his business affairs, labeling the criticism as part of a “coordinated attack” by political opponents.

He resigned before the opposition could formally launch impeachment proceedings. New coalition talks are expected to start shortly to form a new cabinet.
