The Trinamool Congress today alleged that the CPI(M), the BJP and the Congress have joined hands and they were behind the violence taking place during panchayat board formations.

These three opposition parties are terrorising elected candidates of the TMC, its Secretary General Partha Chatterjee told reporters here.

Violence over panchayat board formation has left seven persons dead in various districts of the the state since August 27.

“These political parties have been sent to political oblivion by the people. But they are yet to learn their lesson. Now they have resorted to violence to fight us. Their politics of killing and violence will not yield any results,” he said.

Another senior TMC leader Jyotipriyo Mullick claimed that the BJP and the CPI(M) have joined hands in various parts of the state and have unleashed violence on the ruling party.

“They are stopping our candidates in various places in North 24 Parganas district to stop us from forming boards,” he alleged.

Three persons were killed and 17 others injured in clashes over formation of a panchayat board at Amdanga in North 24 Parganas district yesterday.

The violence followed similar clashes in North Dinajpur, Malda and Purulia districts since Monday in which four persons were killed and several others injured.

Reacting to the violence, Chief Minister Mamata Banerjee, in an apparent reference to the BJP, had said one political party has made the “politics of killing a model”.
