Bersatu president Muhyiddin Yassin has taken a swipe at former premier Najib Abdul Razak over the latter’s remarks questioning his previous cancer treatment abroad.

“He’s not a judge. It’s best that he manages his own problem.

“I have finished issuing my statement and I do not want to add further in this function,” said Muhyiddin during a press conference in Kuala Lumpur yesterday after a function hosted by the Malaysian Future Institute.
