The article considers three interlocking ways in which we can understand the concurrence of antiracismand anti-casteism in the Indian diaspora. First, at the level of experience--ofUKactivists and campaigners--it has been found that the concurrence of anti-racismand anti-casteismis not conclusively determined at this level. Second, by a juxtaposition of the conceptual apparatus of 'caste' and 'race' the article considers the fault lines--illuminating or obfuscating--that appear in conceptualising anti-casteism as a form of anti-racism. Here, the sociality of caste is found to be important, the operation of racialisation underpinning anti-racist practice. Finally, by considering the legal apparatus available in a given jurisdiction (UK), the article evaluates the feasibility of measures thatmight facilitate the actualising of anti-casteism as a form of anti-racism through the practice of litigation to allow a pragmatic capturing of the experience of casteism as a form of racism.
