Dubbing post-poll situation in West Bengal as ‘very bad’, Railway Minister Mamata Banerjee said CPI(M) should learn ‘lessons’ from Nandigram and Singur incidents that ‘lost ground could not be recovered by unleasing terror’.

"After the Lok Sabha poll, law and order in the state became very bad. We had instructed our workers not to take out victory processions which they followed, but the Marxists unleashed attacks in which 22 of our workers were killed," the Trinamool Congress chief said.

"The CPI(M) thinks it will recover lost ground through terror, but they should learn lessons from Nandigram and Singur that this cannot be done," she said and called on people to organise peace rallies against terror.

On state Home Secretary Ardhendu Sen's charges that clashes were on the rise due to change in political equation after the LS polls, Banerjee retorted, "they (CPI-M) committed atrocities and carried outs attacks in the last 7 to 8 days."

Referring to the ‘gruesome’ killing of Khanakul TC leader Yudhstir Dolui in Hooghly district, she said, "his hands and legs were chopped off, his house set on fire and atrocities were committed on women of his household."

She said if clashes had taken place immediately after the results were declared, "we could have been held responsible."
