Recently, the Indian High Commissioner to the UK, Vikram Doraiswami was prevented from entering a Gurudwara in Glasgow, Scotland. This comes amid a diplomatic row between India and Canada over the killing of Khalistani terrorist Hardeep Singh Nijjar. A video of the incident has been doing rounds on the internet, where a man can be seen blocking Doraiswami from entering the Gurudwara. Colin Bloom, former advisor to UK government, said that the Khalistan extremism has escalated due to the inability of Western governments to do enough. Bloom stressed that both the British and Canadian governments should take more proactive measures to address this issue. India has flagged the issue with the UK Foreign Office and also the police, according to sources.
