BJP's Tamil Nadu IT Wing chief CTR Nirmal Kumar on Sunday lashed out against the party's state president K Annamalai and quit the party. Within hours of announcing his resignation, he met AIADMK interim chief K Palaniswami and joined the main opposition party. In a statement uploaded on his Twitter account, Mr Kumar charged the party's state leadership with showing scant disregard to party workers and even alleged Annamalai engaged in "surveillance" against many, a charge denied by a close associate of the leader.
