With elections set for October, the scandal has embarrassed the ruling right-wing nationalist Law and Justice (PiS) party, which has said it is cleaning up an alleged legacy of graft and communist influence tolerated by previous governments. "I plan to submit my resignation tomorrow," Kuchciński told a news conference, three days after he apologised for using government Gulfstream jet for 23 flights with his family. Political analysts said that until Thursday the PiS had adopted a wait and see approach, hoping the scandal would die off amidst the summer holiday lull. But after Polish media published further details of the flights and pointed to discrepancies in explanations by Kuchciński and the government, the potential damage became too serious to gloss over.
