With Mukul Roy quitting the TMC and his Rajya Sabha seat today, the TMC has hinted that Roy had to resign as the BJP had unleashed the CBI after him.
Roy, seen as the right-hand man of Bengal Chief Minister Mamata Banerjee, quit the party and his Rajya Sabha seat today.
"The day CBI went after him, he realized that other than BJP he has no respite," TMC Secretary General Partha Chatterjee told the media.
On Monday, Rajya Sabha MP Roy had said, "Finally, I am going to hand over my resignation to the Vice President on October 11 and then I will tell the people of this country why I decided to end my long political innings with the TMC, the party I founded with many others."
He met the BJP's West Bengal BJP in-charge Kailash Vijayvargiya at the residence of Rajya Sabha House Committee chairperson Om Mathur on Monday.
Roy had said though the meeting with Vijayvargiya was not scheduled, the BJP leader had asked about his plans. He also met Finance Minister Arun Jaitley last week.
The TMC had accused him of hobnobbing with the BJP. Once the second-in-command in the TMC after Chief Minister Banerjee, Roy was suspended for six years for "anti-party activities" last month.
