Chennai, Jan 20: The DMK today decided to boycott the forthcoming Sathankulam by-elections to the Tamil Nadu assembly on February 26, citing the alleged 'misuse' of official machinery by the ruling AIADMK. The decision to this effect was taken at a meeting of the action committee of the party which met here, party president M Karunanidhi told reporters. The party's decision was also prompted by its experience in the previous by-elections, in which there were complaints of inclusion of bogus voters and malpratices in issuing electoral photo identity cards, he said.
