On the 36th anniversary of the infamous Indian army attack on the Sikh nation’s spiritual and temporal seats of authority in Amritsar in June 1984, the World Sikh Parliament has written to the UK’s prime minister calling on him to take his Indian counterpart to task over the issue that has defined the Indo-Sikh conflict over recent decades – India’s unlawful denial of the right of self-determination in the Sikh homeland. The British government’s responsibilities as the former colonial power, the imperative of upholding international law and the need to disavow the foolish complicity of the then Thatcher government, provide sufficient reason to act, according to the global Sikh body.
