Actress Ellie Suriati Omar has called the Pakatan Harapan led federal government a dictatorship.

She based her assessment on supposed deteriorating race relations following Pakatan Harapan's election victory.

With the boom of cannons from the Parliament building audible in the background, Ellie joined Umno supreme council member Lokman Noor Adam and 100 supporters who gathered at a food court near Bukit Aman, about 2km away from the Parliament building.

Lokman said they only wanted to show their "solidarity" and give the Agong "moral support" in the wake of alleged attacks against the monarchy.

Ellie was previously in the spotlight when she was spotted among dozens of former prime minister Najib Abdul Razak's supporters who were chanting "Melayu" repeatedly when attorney-general Tommy Thomas was about to start his press conference at Kuala Lumpur's Jalan Duta court complex.
