Seniorr Congress leader Abhishek Manu Singhvi on Saturday hailed TMC's mega opposition rally here, and said the aim of the rainbow alliance was to defeat the BJP and form a secular government.

Singhvi is representing the Congress at the Brigade Parade Grounds, where leaders of all the opposition parties, except the Biju Janata Dal (BJD)and the CPI(M)-led Left Front, are participating in the rally.

"Never before have we seen such vendetta politics... When Amit Shah did 100 rallies in Uttar Pradesh, no one questioned, but when RJD organised a rally, it got an Income Tax notice," he said.

Congress is an ally of the Lalu Prasad's RJD in the 'Mahagathbandhan' (Grand Alliance) in Bihar. Accusing the government of indulging in "cheap

politics", the Congress leader said the biggest beneficiary of vote division is the BJP.

"(Prime Minister) Narendra Modi makes fun of the opposition alliance, but his party made the most unethical alliance in Kashmir. What would he say about it?" Singhvi said.
