For sake of public interest, Prime Minister Najib Abdul Razak's stepson should disclose the angel financiers behind his rise in Hollywood and how he is able to afford a RM110 million New York penthouse, PKR says.

Doing his own calculation based on his similar working experience, Rafizi Ramli said it was illogical for Rosmah Mansur's son Riza Shahriz Abdul Aziz to afford a RM110 million penthouse in New York, and more so, bankroll a major Hollywood movie.

"Therefore, we want to know who his very generous investors are," Rafizi, who is PKR’s director strategy and the MP for Pandan, told reporters at the party headquarters in Tropicana, Petaling Jaya, today.

"Knowing where the money comes from can (help clear) the public suspicion that the money comes from the family."

Rafizi noted that based on the news article filed by Sarawak Report , even the manner in which Riza's company, Red Granite, financed the Leonardo DiCaprio-starrer ‘The Wolf of Wall Street’ as "unconventional".

It was a concern to many Malaysians as people cannot otherwise comprehend how the families of public officials could live beyond their means, while they struggle with price hikes of basic goods.

The 36-year-old son of Rosmah from her earlier marriage is reported to have bought the seven-bedroom property on Nov 19 last year at 63rd Street in Park Laurel, New York

“His age is about the same as mine. I, too, have a condo but a cheaper condo,” Rafizi said, to laughter in the room.

'Savings may amount to RM150,000 a year'

Giving the standard estimate that an investment banker may earn up to £100,000 a year, Rafizi said that after taxes and expenses, Riza’s savings may amount to a maximum of RM150,000 a year, even if he was a prudent saver.

Over eight years, he may have saved up a million ringgit, Rafizi said. The cost of the New York penthouse is therefore 100 times over.

Riza, according to Sarawak Report, began a banking career after graduating from the London School of Economics in 2000.

The report said Riza had worked with consultancy firm KPMG until 2002 and later at HSBC London until the financial crash of 2008.

“Riza claims they have backing of very supportive financiers from the Middle East and Asia. If they have nothing to hide, then they should really disclose who these financiers are,” he said.
