West Bengal state legislature in Kolkata yesterday plunged into bedlam with ruling Trinamool Congress and Left parties' lawmakers trading blows.

Assembly Speaker Biman Banerjee suspended three Left MLAs, while three injured members were taken to hospital.

Gouranga Chatterjee, a CPI(M) MLA who received head injuries, was taken to hospital as also two Trinamool MLAs Mahmuda Begum who was hit in the chest and Pulok Roy who was injured in the leg.

Tempers ran high after Left members, who wanted to bring an adjournment motion on mushrooming of chit funds in the state, rushed to the Speaker podium and started shouting slogans.

Senior ministers Partha Chatterjee, Subrata Mukherjee and Firhad Hakim shielded the Speaker as Left members continued to shout slogans.

There was pandemonium as CPI(M) member Nazmul Haque snatched the microphone of the Speaker who adjourned the House till 1:30pm.

Congress members, who were asked to join in the protests by the Left, did not respond.

Trouble broke out again after the House reassembled.

Parliamentary Affairs Minister Partha Chatterjee demanded action be taken against Left legislators who insulted the Speaker and snatched away his microphone.

The Speaker thereafter suspended three Left MLAs Nazmul Haque, Sushanta Besra and Amjad Hussain.

One Left member, CPI(M) MLA Deblina Hembram and a Trinamool member were seen engaged in a heated exchange of words.

Subsequently, a free for all ensued in the House with members of Trinamool and Left coming to blows.

Congress members walked out protesting the violence in the House.

Left members also walked out and staged a sit-in demonstration outside the assembly chamber.
