The speaker later told reporters, "After the four MLAs sent a joint letter to me, citing two charges against Suvendu Adhikari. I checked the records this morning and prima facie found the allegations true." "Prima facie there is a case. It is unprecedented and unfortunate that a leader of opposition would use such words in the House. I have never come across such behaviour during my long tenure in the state legislature. This is a criminal offence," Banerjee said. He said the committee will submit its report before the current session ends. The four rebel BJP MLAs — Krishna Kalyani (Raiganj), Tanmoy Ghosh (Bishnupur), Soumen Roy (Kaliaganj) and Biswajit Das (Bagda) — had joined the TMC last year without giving up membership of the House. They have not yet been disqualified under the anti-defection law and continue to occupy the opposition benches. When Adhikari was speaking in the House on the Home Department's budget on Wednesday, they repeatedly interrupted him "for lying and spreading canards against the state government". They later complained to the speaker that when a visibly infuriated Adhikari walked out of the House, he allegedly threatened them with I-T raids for interrupting his speech.
