PKR has listed out four Twitter accounts and three international news organisations which have implicated Rosmah Mansor in the 1MDB affair, in hope that this would be of help to her legal team.

In a statement today, PKR communications director Fahmi Fadzil said his party was responding to Rosmah's threat to take legal action against those who slander her online.

This followed the US Depart of Justice's (DOJ) third court filing to seize assets which were allegedly misappropriated from 1MDB as part of anti-money laundering efforts.

Fahmi's list includes a Twitter account by Al Jazeera Network's sister site AJ+, the Twitter account of the Wall Street Journal economics editor Tom Wright, the Twitter account of WSJ financial reporter Bradley Hope and the Twitter account belonging to Reuters.

He also listed articles by The New York Times, The Guardian and The Straits Times.

"To expedite the process for the legal team, I have identified (these tweets and articles) which clearly tried to link the prime minister's wife with the 1MDB affair, although the DOJ did not mention who was 'wife of Malaysian Official 1'.

"If what was written on Twitter or those websites were defamatory, I urge Rosmah's lawyer to contact the Twitter account or website owners to demand a correction," said Fahmi.

He said it was important to take action on these Twitter accounts and news websites because they were "influencers" with a global following because of their credibility.

"People who read their articles are likely to believe that they were reporting facts. Denials alone would not suffice," said Fahmi.

Meanwhile, Fahmi also urged attorney-general Apandi Ali to order his team to pay the DOJ a visit to clarify matters or reopen the case here in Malaysia.

Fahmi said he also felt compelled to remind Prime Minister Najib Abdul Razak's legal team that the premier had promised on July 5, 2015 to sue WSJ for implicating him in the 1MDB affair.

"Najib's lawyers must act quickly to sue WSJ. If not, public perception on the veracity (of WSJ's report) would remain," he said.

Malaysiakini has contacted Rosmah's aide for comment.

Malaysian authorities have responded to DOJ's latest filing on 1MDB by claiming that the suit does not incriminate Prime Minister Najib Abdul Razak.
