Two Congress lawmakers quit the Gujarat assembly today, apparently after voting against the party candidate in the ongoing by-polls for two Rajya Sabha seats. Alpesh Thakor and Dhavalsinh Zala had rebelled against the party, complaining of unfair treatment. Elections are being held for the seats of Amit Shah and Smriti Irani, who won the recently concluded Lok Sabha election. The BJP is expected to win on account of its numbers.
