The Election Commission (EC) is to convene a special meeting on March 6 to discuss the Balingian state seat to be vacated by Sarawak Chief Minister Tan Sri Abdul Taib Mahmud on Friday.

The meeting, scheduled to begin at 10 am at the EC headquarters in Putrajaya, would be chaired by EC chairman Tan Sri Abdul Aziz Mohd Yusof, said EC secretary Datuk Abdul Ghani Salleh.

A news conference would be held after the meeting, he said in a statement.

Abdul Ghani said the EC was notified officially on Wednesday by the speaker of the Sarawak legislative assembly that the Balingian seat would be vacated by Abdul Taib on Friday.

Abdul Taib is to step down on the same day as the chief minister of Sarawak after having served in that capacity since 1981.

In KUCHING, Sarawak Legislative Assembly Speaker Datuk Amar Mohamad Asfia Awang Nassar said he received a letter from Abdul Taib yesterday stating that he was vacating the seat tomorrow.

He said he notified the EC in writing today on the impending vacancy.

"We leave it to the EC to take the next course of action after the seat is vacated (tomorrow), which will automatically allow a by-election to be held," he told a news conference.

Mohamad Asfia said that as the seat was being vacated more than two years before the expiry of the current tenure of the state legislative assembly on June 20, 2016, a by-election would have to be held by virtue of Section 21 (5) of the state constitution.

He also said that it would be up to the incoming chief minister, Tan Sri Adenan Satem, to decide on the Barisan Nasional (BN) candidate for the by-election.

Adenan, who is Special Functions Minister in the Chief Minister's Office, is scheduled to be sworn in as Sarawak's fifth chief minister tomorrow.

Abdul Taib is scheduled to be sworn in as the new Sarawak Yang Dipertua Negeri on Saturday.
