In September, Prime Minister Justin Trudeau leveled a bombshell accusation in Canada’s House of Commons: He announced there were “credible allegations” India was involved in the killing of a Sikh separatist leader and Canadian citizen, Hardeep Singh Nijjar, in British Columbia in June.

New Delhi immediately dismissed the claims as “absurd” and demanded any evidence be released publicly, which Canada has yet to do. But the diplomatic fallout was swift: Canada expelled the head of India’s security service in Canada, and New Delhi demanded dozens of Canadian diplomats leave India.

On GZERO World, Ian Bremmer speaks with Samir Saran, President of the Observer Research Foundation, a top Indian think tank, to discuss the fallout from the shocking allegations, the history of the Khalistan separatist movement within Canada, and where the two countries go from here, given their strong diasporic and economic links.
