Muhyiddin Yassin said today the attorney-general has affirmed that he was still the prime minister and has yet to be summoned to the palace.

Speaking at a rally in Tambunan, Sabah, Muhyiddin said if he was legally no longer the prime minister, he was sure he would be summoned to face the Yang di-Pertuan Agong.

He promised that should he no longer qualify to be the prime minister, he has two options - either to step down or recommend that the Agong dissolves Parliament.

"If the Agong dissolves Parliament, then Anwar (Ibrahim) will just be a PM-in-waiting," he said.

On Wednesday, Anwar claimed that Muhyiddin no longer enjoyed majority support of the MPs and thus the latter's government had collapsed.

Anwar claimed that he had secured majority support but stopped short of naming his list of supporters pending an audience with the Agong, who is currently receiving medical treatment.

Anwar's claim was reinforced by a statement from Umno president Ahmad Zahid Hamidi, who acknowledged that Anwar now had the support of "many" Umno MPs.

Today marked the first time Muhyiddin had publicly addressed Anwar's claim.

Muhyiddin pointed out that there are doubts since the former has the support of Gabungan Parti Sarawak (GPS) and some Umno leaders.

"I am suspicious. Is (Anwar's claim) real or was it just a political ploy... We will abide by the Constitution," he said, while stressing that constitutionally, he was still the prime minister.

Muhyiddin assured the gathering that he was not power crazy and his priority now was to resolve the problems caused by the Covid-19 pandemic.

He said he doesn't mind if he eventually becomes the shortest-lived prime minister.

"I think I have done my job," he said.
