Mamata Banerjee's party today urged Prime Minister Narendra Modi to remove Tushar Mehta as Solicitor General of India over his alleged meeting with Suvendu Adhikari, a leader of the ruling BJP being investigated by the CBI in corruption cases. Tushar Mehta, who represents the CBI in some of the cases, emphatically denied meeting with Mr Adhikari, saying he "dropped in unannounced" on Thursday.
