In a press release today, PKR strategic director Rafizi Ramli (right) said the project, which was allegedly awarded to a losing bidder, had sullied the Najib's administration's anti-graft pledge.
"PKR will make revelations every two days beginning today about this scandal which will test Najib's commitment in combating corruption and abuse of power," he said.
The coming revelations, Rafizi said, is a response to Umno's "manipulation" of his resignation from the Selangor government to portray a rift in PKR.
Rafizi said that his resignation was purely related to his desire to focus on the general election which is expected soon.
"I advise Najib to handle this coming scandal well for the good for his administration's reputation," he said.
Rafizi was an instrumental figure in uncovering the alleged abuse of a RM250 million soft loan by NFC bosses, who are all related family members of Wanita Umno chief Shahrizat Abdul Jalil.
Shahrizat was eventually not re-appointed as Women, Family and Community Development Minister and her husband Mohamad Salleh Ismail was charged for criminal breach of trust.
Following this, Najib assumed Shahrizat's cabinet post, on top of his role as finance minister.
