Prime Minister Ismail Sabri Yaakob has said there's no certainty whether the so-called PAS leaks document is real.

This was amid a push from Ismail Sabri's fellow leaders in Umno for clarity over the document, which allegedly revealed a conspiracy against the party.

"We don't know whether the document is fake or real," Ismail Sabri told reporters briefly in Putrajaya when asked for comment.
