It will be a crowded fighting field as three independents have confirmed contesting against DAP and Parti Bersatu Sabah (PBS) candidates for the Sandakan parliamentary seat.
Besides DAP's Vivian Wong and Parti Bersatu Sabah (PBS) Datuk Linda Tsen Thau Lin, the independents are former Sabah PAS chairman Hamzah Abdullah, businessman Chia Siew Yung and former political worker Sulaiman Abdul Samat.
The by-election was triggered after two-term incumbent Stephen Wong died of a heart attack following a hike on March 28.
