An Umno leader has challenged Parti Pribumi Bersatu Malaysia (Bersatu) president Muhyiddin Yassin to declare his loyalty to the ruler of his homestate of Johor, Sultan Ibrahim Sultan Iskandar, or former premier Dr Mahathir Mohamad.

As a Johorean, Deputy Transport Minister Abdul Aziz Kaprawi told Umno Online that Muhyiddin should have advised Mahathir against making such controversial remarks, which incurred the wrath of the ruler.
