Former Trinamool leader Mukul Roy submitted his resignation from Rajya Sabha on Wednesday.

The founding member of Trinamool party tendered his resignation to the Vice President and House chairman, M Venkaiah Naidu.

Earlier, speculations were rife that Mukul Roy will join the BJP or form a new political outfit.

“I am not saying I will join the BJP or I will not join (it). Only time will tell. Please wait for a few days,” Roy had recently said.

However, his detractors believed that without Mamata Banerjee, he would be a spent force.

“His political career is going to plunge and will soon cease to exist. His attempts to please the BJP will not bear any results,” TMC secretary general Partha Chatterjee had stated.

On Monday, 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 had also met Finance Minister Arun Jaitley last week.

Mukul Roy was suspended for six years from TMC for ‘anti-party activities’ last month.
