UK Foreign Secretary William Hague told parliament that an official investigation has shown Britain did advise India on planning the controversial Operation Bluestar against Sikh separatists at the Golden Temple in Amritsar in 1984. However, Hague said Britain’s advice had limited impact.

British Prime Minister David Cameron ordered a review into the matter last month after newly released official papers suggested that Margaret Thatcher, then prime minister, had sent an officer from the elite SAS special air service to advise India on the raid.
