Gombak MP Azmin Ali and 10 other independent lawmakers have called for "national reconciliation".
In a statement today, the 11 said Dr Mahathir Mohamad should be allowed to head the national reconciliation effort.
"We are supporting a national reconciliation effort where every Dewan Rakyat member prioritises the aspirations of the public and the national agenda.
"This reconciliation will de-escalate the ongoing power struggle and allow everyone to work together towards common goals and fostering greater good for the nation," the group said.
They added that Malaysians had defeated "kleptocracy" during the last general election and now want a stable government.
"Rehabilitating the economy, generating growth, creating jobs, implementing policies for shared prosperity without considering race or territories - isn't that the people's aspiration?
"To fulfil these aspirations, politicians need to bangkit (rise up) and ditch their narrow partisanship," said the group.
Azmin was sacked from PKR on Feb 24 along with Ampang MP Zuraida Kamaruddin. That same day, nine other PKR MPs then left the party.
Azmin and Zuraida have been accused of triggering a chain of events which ultimately resulted in the dismantling of the Pakatan Harapan federal government.
Azmin had told his supporters during a dinner at the Sheraton Hotel for opposition MPs that they would form a new government with Mahathir serving out a full term.
This had not materialised so far.
Langkawi MP Dr Mahathir Mohamad is currently attempting to establish a new government and is expected to address the nation on live television at 5pm.
