DMK patriarch M Karunanidhi’s condition has seen a significant decline in the last 24 hours, Kauvery Hospital's latest medical bulletin said on Tuesday afternoon as police has been put on high alert across Tamil Nadu. Doctors stated that despite maximum medical support, his vital organ functions continue to deteriorate and his condition is “extremely critical and unstable”. Thousands of Kalaigar’s supporters have gathered outside the hospital, including a large number of women, some failing to control their tears, others waving at the TV cameras, as they pray for a recovery.
