Congress leader Sukhjinder Singh Randhawa on Monday said that he would file a defamation case against Punjab CM Bhagwant Mann for allegedly indulging in his character assassination. Randhawa's statement comes after Mann said that he wouldn't pay ₹55-lakh fee for keeping gangster Mukhtar Ansari in the state's jail and would recover the amount from Amarinder Singh and Sukhjinder Randhawa.
