Congress leader Sanjay Nirupam launched a scathing attack on NCP chief Sharad Pawar and called him a 'poison', claiming that he would not have been unaware about such a move. Sanjay Nirupam also said that People would be thinking I will be happy by today's developments, but I am actually very sad. Congress has been unnecessarily defamed in this and thinking of alliance with Shiv Sena was a mistake.
