An old letter written by Gurpatwant Singh Pannun, leader of the banned Khalistani group Sikhs for Justice (SFJ), has resurfaced online. In the letter, Pannun called on Canadian Prime Minister Justin Trudeau to expel Indian High Commissioner to Canada Sanjay Kumar Verma. Pannun accused Verma of being involved in the murder of Hardeep Singh Nijjar, a pro-Khalistan leader.

The revelation comes amid a deepening diplomatic row between New Delhi and Ottawa. Prime Minister Trudeau took shots at India, accusing the country of being behind the murder of Hardeep Singh Nijjar. Things got worse when Canada labeled Verma and some other diplomats “persons of interest” in the Nijjar murder investigation.
