For now, DMK chief M. Karunanidhi is showing qualified restraint. He did chastise the BJP state unit and declare that the DMK cannot have any truck with it at the state level, describing the signals sent out by it to Jayalalitha as unhealthy. However, he was quick to add that equations in New Delhi had not changed and that the DMK was very much with the NDA. Party MPs admit nevertheless that Karunanidhi is just hanging in, and that he will have to quit the government at the Centre should the AIADMK be accommodated in the NDA. That’s not surprising because since the AIADMK’s impressive showing in the assembly polls last year, there has been much talk of Amma’s return.
