The Trinamul Congress has showcaused its Basirhat MP Idris Ali for using unparliamentary language against the CPIM&’s North 24-Parganas leader Gautam Deb.

Trinamul&’s Rajya Sabha MP and national spokesperson Derek O’ Brien said, “I’ve seen the footage of Idris Ali’s comments. It&’s crass and unhealthy. Party does not endorse such views. He has been asked to explain in writing.

Later, party will take appropriate action.” Mr O’Brien said, “Some in the media are asking what especially was “crass and unhealthy’’ in Idris Ali&’s statement.“We do not endorse the language he used.”

Idris Ali allegedly threatened to cut off the tongue of CPI-M leader Gautam Deb if the latter speaks ill of the chief minister Mamata Banerjee, even as his party disapproved of the statement and called for an explanation.

“Chief Minister Mamata Banerjee is an epitome of honesty. If Gautam Deb speaks ill of her again, I will cut off his tongue and break his bones,” Ali said in response to the former Left Front minister&’s claim that Miss Banerjee would have to go to jail in connection with the Saradha case.

“I will do it even if he hides in the CPI-M state headquarters at Alimuddin Street,” the MP said on Tuesday at the Dadpur village panchayat in North 24 Parganas district’s Sashan area.

The Left party has taken up a programme to gherao the CBI office at the CGO Complex in Salt Lake on 12 January. The CPI-M Politburo member Md Selim, MP, on Wednesday described as “uncivilised and reckless” comments made by Trinamul Congress MP Idris Ali against CPI-M central committee member Gautam Deb and dared the chief minister to condemn such remarks.

“I challenge the chief minister to condemn such utterances made by her party&’s MP since she favours criminal-minded persons to rule the roost in her Trinamul Congress,” Md Selim said.

He alleged that there were lots of instances in which Trinamul Congress leaders, MLAs and MPs had crossed the limit by making highly unsavoury comments “which resemble coming from goons who take the law into their own hands without caring for the law of the land”.
