Amanah and its members are not fanatical followers of anyone, said party deputy president Salahuddin Ayub.
At the same time, he said there was no intent to sideline PKR president Anwar Ibrahim - amid tense speculation that there are moves to pressure the latter to step down as opposition leader.
Speaking at the Amanah Youth convention today, Salahuddin said the party's current goal is to topple Perikatan Nasional (PN).
"There is no intention to sideline Anwar as we are accused of daily. I want to explain Amanah's stance.
"I know Amanah leaders are those most committed to Pakatan Harapan. We don't want to be anyone's walaun (fanatical follower).
"I am not (Amanah president) Mohamad Sabu's walaun. Amanah is not anyone's walaun," he said.
"We are not walaun of (former premier) Dr Mahathir Mohamad, nor Anwar. But we want Harapan to stand and topple the backdoor government," he stressed.
The opposition is in a state of flux after failing to defeat PN in the Budget 2021 debate at the Dewan Rakyat.
DAP secretary-general Lim Guan Eng and Amanah's Mohamad had called for a political reset and a unification of the opposition.
They also urged Harapan to stop hoping for defections from PN.
However, PKR insists that Anwar will be able to secure the numbers needed to form a new government.
Meanwhile, Warisan is pushing for a change of leadership in the opposition which appears to have gained traction among some in Harapan.
Defections to other parties
Salahuddin also encouraged the party's youth leaders to meet with Amanah lawmakers who are considering to defect to another party.
"Go meet them, whether they are an MP or state assemblyperson and ask.
"But if they have set their mind to move to a new 'home', and they are confident that the current 'home' is inadequate or not suitable for them anymore, then I wish them all the best.
"Wish them goodbye and pray for their success. We love everybody, but this is about everyone's right in a democracy. Time will tell who I am, and who you are," he said.
Amanah had seen some of its leaders defecting to other parties.
Titi Serong assemblyperson Hasnul Zulkarnain Abd Munaim left for Bersatu, while Meru assemblyperson Mohd Fakhrulrazi Mohd Mokhtar joined PKR.
During the confidence vote on the then Perak menteri besar Ahmad Faizal Azumu, Hasnul did not vote for him and is said to be the only assemblyperson from Perak Bersatu lawmakers who did not.
Earlier this year, Amanah also sacked lawmaker Ahmad Mustain Othman.
