"Don't keep any relation with those CPI(M) leaders who were involved in the killing of Trinamool Congress workers or such a conspiracy directly or indirectly during their rule," Food and Supply Minister Jyotipriyo Mallick said at a rally here in the North 24-Parganas district.
His earlier boycott call was made in the same district.
"Don't keep in touch with those CPI(M) leaders who murdered Trinamool Congress workers in connivance with the anti-socials and hardcore criminals like Majid Master, Hatkata Dilip, Bulton and Babu Master. Their offence is unpardonable," Mallick said.
"Keep safe distance from these culprit CPI(M) leaders everywhere," he told party workers.
To a question if his directive to the party workers was to boycott the CPI(M) socially, the minister repeatedly said, "This is not a call for social boycott to the CPI(M). Some quarters explained it wrongly and deliberately earlier too."
"Why should we keep in touch with those who killed our workers and supporters? No compromise with their misdeed and anti-social activities...," he said.
