"What happened in the Assembly on Tuesday is deplorable. The incident was an attack on Parliamentary democracy...Women members were also attacked, this had never happened before," CPI(M) MP in Lok Sabha Basudev Acharya, who sat on the dharna, told reporters.
Alleging that workers from the Left parties have been at the receiving end for the last one-and-half-years ever since Trinamool Congress came to power, he said, "No one has the right to speak in the state Assembly neither the government can be criticised. In this one-and-half-year no adjournment motion has been accepted by the House."
"People have seen how democracy is being attacked in the state and rights of the MLAs are being attacked by TMC anti-social elements," he added.
More than a dozen Left leaders including Gurudas Dasgupta participated in the dharna holding placards.
West Bengal Assembly had plunged into bedlam on Tuesday with ruling Trinamool Congress and Left members coming to blows and the Speaker suspending three Left MLAs, while three injured members were taken to hospital.
Tempers ran high after Left members who tried to bring an adjournment motion on the mushrooming of chit funds in the state rushed to Speaker Biman Banerjee's podium and started shouting slogans.
