DAP stalwart Lim Kit Siang has once against risen to defend foe-turned-ally Dr Mahathir Mohamad, this time against activists who fear that the nonagenarian will become prime minister again.

Addressing concerns raised by activist Haris Ibrahim in a news report, Lim said a consensus has not yet been reached among Pakatan Harapan parties on who will become prime minister should the coalition defeat BN in the next general elections.

The Gelang Patah MP reassured Haris that Harapan was committed to ensuring a change in prime minister, and stressed that all Harapan component parties were intent on bringing about reforms to "save Malaysia".

"Haris and other political activists (are) invited to work with the Harapan secretariat to prepare the Harapan reform agenda to save Malaysia," Lim said.

Haris in an FMT report today had said that while he was "thrilled" at the prospect of BN not being in power, he was more concerned about the implementation of reforms.

Lim's remarks come a week after jailed former opposition leader Anwar Ibrahim also moved to defend Mahathir from critics.

Various quarters including former Pakatan Rakyat allies Parti Sosialis Malaysia (PSM), and Anwar's hardcore supporters in the Otai Reformasi group, have voiced their displeasure with Mahathir's presence in the opposition coalition.

Otai Reformasi has called on Harapan to include a pledge to probe Mahathir for his alleged past misdeeds in its election manifesto.
