The police will quiz Umno lawmaker Nawawi Ahmad over his Facebook comment linking the Yang di-Pertuan Agong to Malaysian Official 1 (MO1), said inspector-general of police Khalid Abu Bakar.

"We have received the (police) reports and investigations are underway.

"Yes (we will record his statement), that is part of the investigation process," he told a press conference in Kuala Lumpur this afternoon.

Meanwhile, Perkasa Youth handed a memorandum to the Yang di-Pertuan Agong calling for His Majesty to take action against the Langkawi MP.

Perkasa Youth chief Irwan Fahmi Ideris said the Agong, who is also the Kedah Sultan, should revoke Nawawi’s datukship.

Irwan also urged the police to take action since five reports had been lodged on the matter.

"Don't hide (the case), we want action. We want him to be charged. We want the police to play their role in defending the royal institution," he told reporters after handing a memorandum on the matter to an official at Istana Negara.

Perkasa integrity, anti-corruption and abuse of power bureau secretary Dr Muhammad Faiz Na'aman criticised Nawawi for terming the ruler as an official.

"MO1 means official number one. The Agong is not an official. If Nawawi as a MP does not understand national affairs, than he is stupid," he added.

On Tuesday, Nawawi in his Facebook comment, which was edited four hours later, said based on the Federal Constitution, it is the Yang di-Pertuan Agong who is responsible for the government.

"According to the Federal Constitution, Malaysia's government was formed with three separate and independent entities – the judiciary headed by the chief justice, the legislative led by the parliament speaker, and the executive directed by the prime minister.

"All three entities are responsible to the Agong. Hence, according to the constitution, MO1 is the Agong," he said.

In the edited version, the last line in the comment was replaced with the sentence, "Hence, according to the constitution (Prime Minister) Najib (Abdul Razak) is not MO1, as he is either MO2, MO3, or MO4."

He has also clarified that he was talking about Malaysian Official "Number" 1, and not the MO1 mentioned in the US Department of Justice suits related to 1MDB.
