In New Delhi on 23 November, a motley of left-leaning and radical groups gathered under the cover of “anti-pollution” protests. While the public concern was air quality, many of the participants used the platform to express deeper political grievances. Among them were outfits known for their pro-Naxal leanings — notably Bhagat Singh Chhatra Ekta Manch (bsCEM) and The Himkhand.
