Trinamool Congress (TMC) MP Saumitra Khan on Wednesdy joined the Bharatiya Janata Party (BJP), dealing a blow to Mamata Banerjee-led party ahead of the Lok Sabha elections.

"Soumitra Khan joining the BJP is just a trailer. The full-length feature is yet to be seen. Be sure that TMC will be extinct before 2021," remarked Mukul Roy, a BJP leader who was earlier a close confidant of Mamata Banerjee before changing over.

Khan, a member of Lok Sabha from Bishnupur in West Bengal, joined the BJP at its party headquarters here in presence of Union Minister Dharmendra Pradhan. He joined the party hours after being suspended from Trinamool.

After being inducted in the BJP, Khan called Banerjee a Hitler.

Former union minister Mukul Roy, who was also present when Khan joined the party, said the countdown for West Bengal chief minister Mamata Banerjee has begun.

"Countdown started for @MamataOfficial Devi, your MP and MLA’s will leave you one after another and Loksabha 2019 will bring an end to your misrule," he tweeted.

Addressing the media after Khan's induction into the BJP, Roy said, "Soumitra Khan joining the BJP is just a trailer. The full-length feature is yet to be seen. Be sure that TMC will be extinct before 2021."

Roy also informed that there are more than five MPs who are not happy with the TMC and the BJP is holding talks with them.

If speculations are to be believed, Hazra, too, is likely to join the BJP.
