Kolkata, Feb 11 : Nobel laureate Amartya Sen has finally sent a legal notice to the Visva Bharati University authorities asking the latter to tender a public apology for their derogatory comments in connection with the continuing row over 13 decimals of land occupied by him.

Sen's counsel Gorachand Chakroborty informed media persons on Saturday that a globally acclaimed educationist like Professor Sen is being defamed by raising baseless allegations against him about illegally having possession of 13 decimals of land in excess of its legal entitlement for 1.25 acres. "The university authorities should apologise for making such derogatory comments. Else appropriate legal actions will be taken," Chakroborty said.
