Communications and Multimedia Minister Salleh Said Keruak has advised Dr Mahathir Mohamad to heed the scathing admonishment from Johor ruler Sultan Ibrahim Sultan Iskandar.

Salleh argued the fact that the ruler was forced to rebuke Mahathir showed the former prime minister had crossed the line of decency, which the sultan could no longer tolerate.

“Today, the Sultan of Johor gave the worst-ever dressing down to who he referred to as a demented-leader, who many believe His Highness meant Dr Mahathir.

“And this is not the first time Mahathir has been given an earful by His Highness, mind you. It would be wise for Mahathir to heed what His Highness said.

“Mahathir now appears unable to separate his personal grudge from the interest of the nation. Mahathir is bringing ridicule upon himself and he has only himself to blame for it,” Salleh said in a blog post.
