The fourth prime minister Dr Mahathir Mohamad walks past a portrait of his predecessor Abdul Razak Hussein, who was the second prime minister of Malaysia.

Mahathir was in Parliament on March 27 to chair the Pakatan Harapan presidential council meeting.

He served as prime minister and Umno president for 22 years until 2003, but is now aligned to the opposition, vowing to unseat the sixth and present Prime Minister Najib Abdul Razak, who is Abdul Razak's son.
