Almost a year after the botched Rantau election resulted in a walkover, Umno acting president Mohamad Hasan will finally face off against PKR's Dr S Streram in a by-election.

A total of four candidates will be contesting, namely Harapan's S Streram, BN's Mohamad Hasan and two aspiring-independent candidates R Malar and Mohd Nor Yasin.
