Sir — It is heartening that a few leaders from the All India Anna Dravida Munnetra Kazhagam, visited the Kauvery Hospital to enquire about the health of Dravida Munnetra Kazhagam chief M Karunanidhi, who is undergoing treatment at the hospital. A new and healthy trend is emerging in Tamil Nadu politics. One only wishes that this transformation stays for ever, irrespective of the leaders’ political affiliation.
