Pandan MP Rafizi Ramli has launched a public petition urging the Yang di-Pertuan Agong and Malay rulers to re-open investigations against Prime Minister Najib Abdul Razak.

The PKR lawmaker also called on attorney-general Mohamed Apandi Ali to approve the Malaysian Anti-Corruption Commission's request for Mutual Legal Assistance (MLA) overseas.

In his statement today, Rafizi urged the public to like the '1 Juta Desak Buka Kembali Siasatan Terhadap Najib Razak' (1 million call for investigations against Najib Razak to be re-opened) Facebook page , and to sign an online petition .

The petition urges the Conference of Rulers to not only re-open the probe, but to appoint an independent prosecutor to head the investigations.

The petition comes two weeks after Apandi absolved Najib of any wrongdoing, and ordered the MACC to stop its investigations into the RM2.6 billion donation and SRC International scandals.

Apandi had also said there was no need for him to sign off on the MACC's MLA request as there was no criminal offence in the donation.

However, the AG told Sin Chew Daily yesterday that the graftbuster can resume investigations if it finds new evidence.

'Not royal donation'

Rafizi wants the case to be revived following a comment by Saudi Arabia's Foreign Minister Adel al-Jubeir that the RM2.6 billion was an "investment" from a "private individual", and not a royal donation.

The PKR secretary-general said this is highly suspect, as Najib is not a businessman nor is he an investment expert.

He added if it was an investment, the investor would have wanted something in return, creating a conflict of interest because of the various high level portfolios Najib holds.

Rafizi said the Arab investment also reignites speculation that the RM2.6 billion is related to 1MDB, as the sovereign wealth fund had boasted of its investments involving Arabs.

Najib has denied any wrongdoing, as well as allegations that he misused public funds.
