Dr Mahathir Mohamad's resignation as prime minister on Feb 24 brought the curtain down on Pakatan Harapan's 22-month-old government.

His close confidante Daim Zainuddin, in an interview sent to several media outlets, is asked if the nonagenarian, who is often regarded as a master in statecraft, had made a mistake.

Alluding to the Bersatu supreme council meeting the morning before the resignation, he said Mahathir needed to act fast.
