Nobel laureate Amartya Sen has written to Bengal Chief Minister Mamata Banerjee today, thanking her for support in the controversy over his ancestral property in Santiniketan. The Visva Bharati University has reportedly written to the Ministry of Education, listing encroachers on campus land and Professor Sen's name was on it. The 87-year-old laureate has completely dismissed the reports, saying he had read about the controversy in the media and no one from the University had got in touch with him.
