The Kuala Lumpur High Court is set to rule on Najib’s application in June.

“You can say whatever you like. We will have to do our job, continue with our reforms.”

Anwar also bristled at accusations that PKR had abandoned its reform promises, arguing that critics had been quick to cast judgment based on the actions of the party’s coalition partner, Umno, while ignoring his administration’s work to bolster the economy and Malaysian democracy.

Ahmad Zahid was Najib’s former deputy and is now Umno’s president – a sign, critics say, of the compromises that have been required of Anwar to attain the prime minister’s office.

While many PKR leaders and rank-and-file members have publicly closed ranks behind the Malaysian prime minister, in private others say they are worried about the reputational damage to his government if Najib is offered house arrest on Anwar’s watch.

“I don’t think this will blow over. When a coalition partner does something, we will have to face it later on,” one party member told This Week in Asia, asking not to be named as they were not authorised to speak to the media.

Former party leader N. Surendran, who quit PKR in February following Najib’s sentence reduction, was more scathing of a political outfit that this week marked its anniversary from a position of power after decades frozen out in opposition.

“What’s to celebrate? For 25 yrs they promised reform. In power – no reforms, only excuses,” he said in a post on X on Sunday.

“Those of us who fought & risked jail to bring PKR to power, fought for nothing. It’s a morally dead party, propped up by the trappings of power, focused only on staying in power.”

Some PKR party members have echoed Anwar’s position that the government should not interfere with the judiciary and allow Malaysia’s courts to dispose of any and all cases independently, regardless of who is involved.

“The prime minister has said that at the end of the day the decision lay with the pardons board and the king. It is up to the court to review,” said deputy youth chief Muhammad Kamil Abdul Munim, referring to Umno’s backing of Najib’s push for house arrest.

“Malaysia practises democracy, and we can’t stop anyone from pursuing things that they believe are within their rights.”

Lee Chean Chung, another PKR lawmaker, said the only thing the party and government could – and should – do is stick to their guns and allow the courts to operate independently, as PKR had long promised.

“This is more important than changing views on issues. If an institution is perceived to be compromised, it will have long term consequences,” Lee said.
