Rizal Mansor, aide to prime minister’s wife Rosmah Mansor, has described Tanjong MP Ng Wei Aik as “naive” for failing to get his boss’ sarcasm.

This was after Ng declared that Rosmah had admitted to being the wife of ‘MO1' (Malaysian Official 1) when he asked her about it.

“Clearly, he can be stamped as a naive person because he cannot differentiate between serious.

“Datin Seri (Rosmah) has a higher intellect compared to the DAP MP.

“So, when he teased her, she responded with sarcasm... can’t he understand?” Rizal said in a statement today.

Rizal said Ng should instead focus on Budget 2017.

“When Budget 2017 was tabled, he colluded (with other opposition MPs) to leave the Dewan Rakyat, even though it was an important matter to the country and people.

“The Tanjong MP is not qualified to become an elected representative.

“He has not reached that level yet,” he said.

Last Friday, Ng wrote on his Facebook that he had asked “who is the wife of MO1" while passing by Rosmah.

He claimed that Rosmah replied: "Yes, I am. You think I am scared of you?"

When contacted, Ng claimed the exchange happened in the Dewan Rakyat, during the opposition's walkout last Friday.

Rosmah was seated behind the opposition lawmakers in the House while her husband Prime Minister Najib Abdul Razak tabled Budget 2017.

The opposition had walked out in the midst of Najib's speech as he began taking shots at them.

They had stood up holding ‘Siapa MO1’ (Who is MO1) placards, chanting "MO1, MO1" before leaving the Dewan Rakyat.

MO1 is a public official whom the US Department of Justice claimed received US$731 million allegedly stolen from 1MDB.

Minister in the Prime Minister's Department Abdul Rahman Dahlan has said that MO1 is the prime minister.

Meanwhile, DAP Batu Kawan MP Kasthuri Patto said she too had an exchange with Rosmah.

Kasthuri claimed that as the opposition MPs were walking out, the prime minister's wife "sarcastically" told them repeatedly: "Thank you for coming."

The MP said this was against House rules "as guests are seen and not heard" unless given permission to speak by the speaker.

"So I confronted her and told her that while she is in the House, she should learn the rules, and she was shocked," Kasthuri told Malaysiakini.
