The Rejinagar seat fell vacant after Aam Janata Unnayan Party chief Humayun Kabir retained Nowda after winning both constituencies.
The Nandigram contest includes candidates from the BJP, the Mamata Banerjee-led TMC faction, the rival TMC faction and the Left, among others. In Rejinagar, the BJP, Congress, CPI(M), TMC factions and Kabir’s AJUP are among those in the fray.
In Tamil Nadu, bypolls are being held in Madurantakam and Dharapuram after the sitting AIADMK MLAs resigned and joined the ruling TVK. The contests are also being closely watched as a major electoral test for actor-politician Vijay’s party.
