Former AICC spokesperson Tom Vadakkan joined the BJP on Thursday.
Vadakkan received the party membership from senior BJP leader and Union Law Minister Ravi Shankar Prasad.
Vadakkan said he was leaving the Congress in protest against the party's stance on Pulwama. He said the developments initiated by Prime Minister Narendra Modi also attracted him.
Vadakkan's political activities were confined to Delhi where he served as a spokesperson of the party. He did not have a major role in the Kerala unit of the party.
