Postal votes, which draw much attention as this particular state seat holds the most of it, started at 8am and is expected to finish at 5pm.
Only one agent is allowed to represent both candidates, namely Tan Sri Isa Samad of Barisan Nasional and Zulkefly Mohd Omar of Pakatan Rakyat.
PR, in its campaign since the nomidation day on Oct 3, has manipulated the issue of postal votes, accusing the government of votes rigging and other voting discrepancies. During the last general election, PR managed to garner about 1,700 postal votes.
Election Commission officials said if voting is not completed by today, it will be extended to tomorrow to enable all soldiers to cast their votes.
All ballot bags must reach the returning officer by 5pm on Sunday or it will not be counted.
