Former RAW chief Sanjeev Tripathi today joined the BJP ahead of the Lok Sabha elections, following the footsteps of several retired bureaucrats and diplomats finding a career in politics.

Tripathi, a 1972-batch IPS officer, is the latest to join the saffron party in the recent past after former Home Secretary R K Singh, former Petroleum Secretary R S Pandey and India's former permanent representative at the UN Hardeep Singh Puri.
