The party's criticism of the governor comes a day after Chief Minister Mamata Banerjee accused Tripathi of threatening her and acting like a "BJP block president". The party supremo said she even thought of quitting office over this "humiliation".
Speaking to reporters, TMC Secretary General Partha Chatterjee charged, "The governor has crossed the constitutional line. The way he spoke to the chief minister yesterday, he has forgotten that it is not Uttar Pradesh."
"He is the ex-speaker of the (UP) assembly. As a lawyer he must be aware of the observation of the Supreme Court (on the relation) between the chief minister and the governor... So whatever he has said is an insult to the people of West Bengal," he charged.
The unprecedented spat between the chief minister and the governor came as communal clashes broke out in West Bengal's North 24 Parganas district on the night of July 4 following an "objectionable" Facebook post. The government rushed in 400 BSF troopers to assist the local administration in controlling the situation.

A copy of the letter to the president was forwarded to Home Minister Rajnath Singh, he said.
Referring to the governor's statement yesterday asking how confidential talks came out in the open, Chatterjee said, "You (Tripathi) telephoned the chief minister only after a team of BJP leaders met you at Raj Bhavan".
A Raj Bhavan statement had yesterday said that the talks between the governor and chief minister "were confidential in nature and none is expected to disclose it".
To a question on whether the TMC was demanding the governor's removal, Chatterjee said, "If the governor does not express regret for the way he had spoken to the chief minister, we will have to take the tough stand."
