Opposition PASOK leader Nikos Androulakis accused polling firms of manipulating public opinion Thursday, after two surveys showed his party trailing the new party of former prime minister Alexis Tsipras.

“Some people aren’t conducting polls. They’re manipulating public opinion,” Androulakis said in an interview on Open television.

PASOK officials pointed to a stark contradiction: One poll by Interview showed just a 0.5 percentage point gap between PASOK and Tsipras’ ELAS party, while RealPolls put the difference at eight points. “It’s obvious both cannot be true,” the party said in a statement.

Androulakis drew sharp contrasts between himself and his rivals, attacking both Prime Minister Kyriakos Mitsotakis and Tsipras. He accused Tsipras of hypocrisy for claiming solidarity with struggling borrowers while having “sold billions of euros in red loans to funds” through legislation he passed as prime minister.

He expressed confidence voters would ultimately judge “who has a path free of dependencies and without the support of the domestic oligarchy, and who has protectors and sponsors.”
