Rahul Gandhi’s sudden air dash to Chennai to see Tamil Nadu Chief Minister J Jayalalithaa took everyone by surprise. No one, much less state Congress chief S Thirunavukkarasar, had any information about the visit. Once he found out, Thirunavukkarasar tried to contact leaders in Delhi to confirm the news. State Congress leaders are now calculating the impact of Rahul’s visit on the party’s equation with the DMK, especially ahead of local body elections. Some party leaders believe the visit might not have gone down well with the DMK, whose leader M Karunanidhi had asked the state government the other day to release photographs of Jayalalithaa to end rumours about her health. Rahul did not meet any DMK leaders and left within two hours of landing in Chennai.
