Prime Minister Najib Abdul Razak may have threatened legal action against Wall Street Journal ( WSJ ) but he should also sue former premier Dr Mahathir Mohamad.

Umno blogger Shahbudin Husin, said this was to prove that Najib's claims of Mahathir perpetrating the allegations of financial scandals against him held water.

He was referring to Najib who fingered Mahathir yesterday over a WSJ report alleging US$700 million (RM2.6 billion) of 1MDB's funds had been deposited into the prime minister's private bank accounts through proxies.

Shahbudin noted that Najib's political secretary Khairun Aseh had said that Najib planned to take legal action against WSJ but made no mention of Mahathir despite the prime minister accusing him of being the mastermind .

"If Najib dares to accuse the former prime minister of 22 years of being the mastermind, then he surely would have evidence to back his claim," said Shahbudin in a blog posting today.

Shahbudin, who is Mahathir's ally, said if Mahathir was the mastermind of the shocking expose, then he is the first person Najib must sue.

"If it is true that Najib has evidence about Mahathir's role or involvement as the mastermind in the WSJ report, action should be taken against the mastermind before WSJ or Sarawak Report ," he said.

'Go after mastermind first'

Shahbudin added if the mastermind was not tackled, then the latter could always use other platforms apart from WSJ to attack Najib.

Otherwise, Shahbudin said it will be Mahathir who could sue Najib for false accusations.

Yesterday, WSJ and whistleblower website Sarawak Report concurrently ran reports alleging Najib had received US$700 million from 1MDB's funds shortly before the last general election.

Najib has since denied taking government funds for "personal gain" and accused Mahathir of perpetrating the claims against him.
