Ghosh headed Sen's media units, which were known for steadfastly supporting Trinamool and its supremo and Chief Minister Mamata Banerjee.
Beside Ghosh, Trinamool MPs Tapas Pal and Shatabdi Roy addressed the rally in the city alongside rebel legislator Shikha Mitra, whose husband and Lok Sabha member Somen Mitra was also present. Somen Mitra's loyalty to the party has also long been questioned.
Trinamool national general secretary Mukul Roy said the party's disciplinary committee met in the evening and decided to show cause Ghosh, Roy and Pal for "anti-party activity" and for hurting its image. "The letter would be served on them within a couple of days, he said.
In an apparent attack on the party leadership, Ghosh said: "The burden of the Saradha scam has been put on my shoulders. Those who have been firing from my shoulders, I won't concede an inch to them. I won't allow them to hush it up."
"I have already said I am ready to face probe by any agency. I have full confidence in the detective department of police. I had also earlier written a letter saying I have no problem if the CBI is asked to investigate the case. Let those whose names figure be probed," said Ghosh, who was earlier quizzed in connection to the scam - considered the biggest to hit the state.
