Trinamool Congress MP Abhishek Banerjee on Monday sent a defamation notice to Bharatiya Janata Party leader Mukul Roy for levelling corruption allegations against him in a rally.

Roy, who joined the Bharatiya Janata Party on November 3, on Friday had alleged that Banerjee, the nephew of West Bengal Chief Minister Mamata Banerjee, owned Biswa Bangla, a brand promoted by the state government. He had also said that the All India Trinamool Youth Congress national president owned the party’s mouthpiece Jago Bangla.

“Biswa Bangla, sponsor of the recent Under-17 FIFA World Cup, is owned by Abhishek Banerjee,” Roy had alleged at his first public rally in Kolkata since he joined the BJP. “It is not a government entity. All campaign material, party literature, monograms, etc of Trinamool Congress are printed by a company owned by Abhishek Banerjee,”
