Umno minister Mohamed Nazri Abdul Aziz said he would have died on the spot instead of just "almost faint" if he had seen RM4 billion in Prime Minister Najib Abdul Razak's private bank account.

He said this when he took a swipe at former deputy prime minister Muhyiddin Yassin, who claimed last week that he almost fainted when he was showed the amount in Najib's account.

"Why didn't he faint then, why (merely almost) fainted? He should have fainted if it is true," he quipped.
