In a radio interview on Wednesday, Law and Justice (PiS) member Paweł Poncyljusz said that his party needs to adopt a more balanced, conciliatory rhetoric.

Mr Poncyljusz, who helped organize Jarosław Kaczyński's election campaign, was marginalized after the elections were won by Civic Platform candidate Bronisław Komorowski.

“This [current PiS] rhetoric will keep PiS in the opposition benches,” said Mr Poncyljusz on radio RMF FM. “I would prefer Jarosław [Kaczyński] to be like he was during the election campaign.”

When running for president, Jarosław Kaczyński moved away from his usual hard rhetoric and focused on cooperation and inter-party understanding, avoiding talk of the Smolensk plane crash in which his brother, Lech, and 95 others died on April 10.

After the campaign had ended, PiS shifted its attention to the tragedy, heavily criticizing the government for its treatment of the investigation into the crash, and sparking conspiracy theories in the process.

But Mr Poncyljusz vehemently opposed the suggestion that Mr Kaczyński's “new face” during the campaign was just a pose. According to him, it simply represented what Mr Kaczyński felt at the time.

He also thinks that the present rhetoric is a road to disaster. “This strategy is for 20 percent of support maximum and we know well that with the present opinion poll results for other parties, this means that Law and Justice will always stay in the opposition benches,” he said.

This is just the latest of a number of recent remarks by representatives of PiS's “liberal” wing. Others have also urged Mr Kaczyński to return to a more balanced discourse in order not to marginalize his party.
