Umno's Sembrong MP Hishammuddin Hussein will face his party's disciplinary committee on Dec 26.

This follows his alleged involvement in a gathering of Umno MPs at PKR deputy president, who is also Economic Affairs Minister, Mohamed Azmin Ali's official residence on Nov 19.  

When contacted, Umno disciplinary board chairperson Mohamed Apandi Ali confirmed that a letter summoning Hishammuddin had been sent to the former Umno vice-president.

"I confirm that a show-cause letter has been delivered," Apandi told Malaysiakini when contacted.

Immediately after the gathering, Umno supreme council member Lokman Noor Adam had accused Hishammuddin of rallying Umno MPs for Azmin.

Lokman also revealed that he had lodged a complaint against Hishammuddin on Oct 30 and urged the party to take action. Lokman had claimed Hishammuddin was responsible for orchestrating the defection of Umno MPs to Bersatu.

This was amid speculation that Hishammuddin and Azmin were working together to gather enough MPs to ensure Dr Mahathir Mohamad can stay on as prime minister and to thwart PKR president Anwar Ibrahim's rise.

Hishammuddin had denied the allegations against him.

In an immediate response, Hishammuddin said he has no qualms to be investigated by the party.

"My position is consistent — if they want to investigate, then go ahead and investigate. I have nothing to hide," he said in Facebook post.

He stressed the majority of Umno members were still loyal to the party's cause.

He also highlighted Umno president Ahmad Zahid Hamidi's statement that all Umno MPs must remain loyal to the party.

"So, don't complicate the situation with speculations," Hishammuddin added.
