Polling day for the Rantau by-election has arrived.

BN acting chairperson Mohamad Hasan has held the seat for over 14 years, and his coalition is looking for a hattrick today following its wins in Cameron Highlands and Semenyih.

A total of 20,804 voters are eligible to cast their ballots today for either Mohamad, PKR's Dr S Streram, or independent candidates R Malar, and Mohd Nor Yasin.
