The CPI(M) Politburo took the decision following Chatterjee's defiance by not quitting the post of Lok Sabha Speaker after the Left parties' withdrawal of their support to the UPA government. However, it is still uncertain whether Chatterjee will quit from his post as a speaker. The politburo member Biman Bose said that the Speaker has violated the party's constitution by not heeding requests to quit his post as Speaker and vote alongside the party in the concluded Trust vote on Tuesday.
Chatterjee has been under intense pressure from the CPI(M) to resign after the party withdrew support to the government and even listed him as among the party MPs who had withdrawn support.The CPI(M) wanted him to toe the party line but he defied and remained in the post. Lately, there have been reports that he planned to resign after conducting the confidence motion.
