The BJP on Wednesday took a swipe at former RBI governor Raghuram Rajan after he joined the Congress` `Bharat Jodo Yatra` and said his commentary on India`s economy should be discarded with "disdain" as it is "coloured and opportunistic".

BJP`s foreign affairs department head Vijay Chauthaiwale tweeted, "One former RBI governor became head of govt and country lost ten precious years. Thanks to Modi, India will not repeat that mistake. RRR (Raghuram Rajan) can walk from Delhi to Chicago."
