OTTAWA — NDP Leader Jagmeet Singh declared Thursday that he accepts the findings of the Canadian inquiry into the Air India bombing and condemns all that were behind the horror that killed more than 300 people off the coast of Scotland in 1985.

That includes Sikh extremist Talwinder Singh Parmar, identified by Canada's Air India inquiry as the mastermind of the attack. In a column posted Thursday by The Globe and Mail, Singh also attempts to explain why it has taken him until now to explicitly condemn Parmar, as well as those in the Sikh community who choose to display his photo in places of honour.

"While the Air India Inquiry did not result in convictions, its findings identified a man named Talwinder Singh Parmar as the mastermind of the attack," Singh wrote. "I accept those findings and condemn all responsible for the horror they inflicted.

"Some in the Sikh community have not accepted the official record of events. While I can understand that pain, my approach has been different: I have always tried to give space to all voices so that we can move together toward peace and reconciliation."

Singh says he has been asked to condemn terrorism many times and always has and always will.

The opinion piece comes as Singh finds himself defending his appearances at a number of other events in recent years which promoted the idea of Sikh independence, including one in which he is seen sitting quietly beside a Sikh leader in England who says his vision of Sikhism endorses "violence as a legitimate source of resistance and survival."

Singh needs to do more to denounce such sentiments, said Ujjal Dosanjh, a former federal Liberal health minister, ex-premier of British Columbia and a Sikh who is a vocal critic of Sikh separatism.

A politician standing next to a fascist doing a Nazi salute is expected to speak out, as is a politician standing next to someone who promotes violence in the name of a cause, Dosanjh said in an interview.

"Unless he totally disavows that and much more, he shouldn't aspire to lead a political party, to be the prime minister of the country," he said.

"That's not to say he's not a good man but his views that come across from many of these things are views that are totally antithetical to the idea of a secular Canada."
