The temperature in Amritsar, at 42 degree Celsius, would have been in stark contrast to chilly Ottawa when Harjit Singh Sajjan prayed at the famed Golden Temple. But a different kind of heat was building up over the visit of Canada’s defence minister to his parents’ land. Capt Amarinder Singh, now back in the saddle as Punjab chief minister, invoked an old festering wound a week ago to make a dramatic, unusual statement: no meeting this foreign dignitary. The reason Amarinder offered: Sajjan and some other Sikh-origin cabinet ministers and parliamentarians in Canada were Khalistan sympathisers. For what should have been a diplomatic affair full of courtesy and nostalgia, the fat was truly in the fire.
