KUALA LUMPUR, Aug. 4 (Xinhua) -- Malaysia's Prime Minister Muhyiddin Yassin said on Wednesday that he will seek a confidence vote in September to decide if he commands majority support among members of the country's lower house of parliament.

Muhyiddin said in a televised speech that he still held the support of a majority of members of parliament (MPs) and had informed the country's King Sultan Abdullah Sultan Ahmad Shah.

"A motion for a vote of confidence in me will be tabled in the lower house when parliament convenes in September," he said.

The upcoming parliament session is scheduled from Sept. 6 to 30.

Muhyiddin's announcement comes after Ahmad Zahid Hamidi, president of the United Malays National Organization (UMNO), a component of the ruling Perikatan Nasional (PN) coalition, announced withdrawing support for the prime minister.

Muhyiddin has been holding on to power with a slim majority and the withdrawal of UMNO could see him having an insufficient number of MPs to continue governing.
