Sanjay Kumar Verma, the Indian High Commissioner to Canada, before departing from Ottawa accused Canadian Prime Minister Justin Trudeau of ruining the bilateral ties for political gains.In an interview with Canada's private broadcaster CTV, Sanjay Verma said, "Canada didn't follow the practice which should have been there. Evidence should have been shared first, but someone (Trudeau) decided to stand in Parliament and talk about a thing for which he himself has said there was no hard evidence.""And the day on which he did that, since then, he has made sure that the bilateral relations with India only go downwards, spiraling down," he added."The problem is that when he was accused, he himself admitted there was no hard evidence. There was intelligence. On the basis of intelligence, if you want to destroy a relationship, be my guest," Verma said.Verma said that the evidence being cited by Canada is hearsay. "I know, for sure, that they go from one person to the other, asking them about the hearsay. Most of them are those who are pro-Khalistan elements, anti-India elements," he said.Verma also highlighted Western hypocrisy, saying "gone are the days when the so-called developed countries would ask a developing country that you must do this, and they will run after them and do it".Verma said he and his colleagues were monitoring pro-Khalistan and anti-India elements in Canada, but not using any covert means. "We read the newspapers, we read their (pro-Khalistan groups) statements. Since we understand Punjabi, we read their social media posts and tried to infer them," he said."If the Canadian politicians are so novice that they want me not to know what my enemies are doing here, then I'm sorry, they don't know what international relations is all about," Verma said."I know the countries which have done it (extrajudicial killings on foreign territory). And some of them are G7 countries, by the way. So let's not talk about it. There should not be double standards," he added.
