PAS is seeking to raise RM400,000 from the public to meet the cost of its president's legal suit against whistleblower website Sarawak Report.
Party vice-president Idris Ahmad said the amount needs to be paid in two weeks time to the lawyer in London where the case is being heard.
"We badly need assistance [...] the funds raised now is only RM69,000. We need another RM331,000," he said in a statement today.
PAS president Abdul Hadi Awang had sued Sarawak Report editor Clare Rewcastle-Brown for libel in London on April 21, 2017.
It is related to the portal's report on August 6, 2016, which alleged that PAS received RM90 million to ensure the party's support for BN and Umno.
Idris said that there will be more legal bills in the future as the case proceeds.
"We already paid close to RM2.5 million. The campaign needs at least a RM10 per person donation," he said.
