The Jammu and Kashmir unit of the BJP served a legal notice to Chief Minister Omar Abdullah on Monday through its president Sat Sharma, describing Abdullah's claims of a Rs 20-30 crore bribe and ministerial berth offer to an NC legislator as false and defamatory. The notice demands a public apology within seven days and threatens civil and criminal defamation proceedings plus Rs 100 crore in damages if unmet. Abdullah made the allegations on July 11 at an event in Srinagar.
