Former Reserve Bank of India (RBI) Governor Raghuram Rajan joined the Rahul Gandhi-led Bharat Jodo Yatra on Wednesday, initiating a debate on whether economists like Rajan can take part in political rallies. The ruling party and some segments of media did not take the top economist’s presence at the yatra lightly. Bharatiya Janata Party’s (BJP’s) IT cell chief Amit Malviya even termed it a “coloured and opportunistic” involvement.
