AIADMK MLA Sekarbabu defects to DMK

With the Tamil Nadu Assembly polls round the corner, DMK on Saturday received a shot in the arm when its arch rival, AIADMK's Chennai strongman and MLA P K Sekarbabu defected to the ruling party. Sekarbabu, who was recently removed as AIADMK's North Chennai unit Secretary, on Saturday called on chief minister and DMK chief M Karunanidhi and joined the party, becoming the fifth MLA to leave the principal opposition party since the last Assembly polls in 2006.
