NEW DELHI: The UK government , though busy with BREXIT deal, will be once again put to test, when Pak-backed Kashmiri groups plan to hold protest against India on October 27 coinciding with the Diwali festivities. Kashmiris living in Burton are planning to visit London to take part in "an anti-India demonstration" on October 27 to be marked as "black day by the Kashmiris". On August 15, the British government had failed to safeguard the Indian High Commission that was attacked by pro-Pak groups creating a disquiet in Delhi.Members of the Kashmir Forum and the mosques in Burton have arranged free coaches to take people to the planned major protest on October 27, according to some reports.The protest plans to begin outside Downing Street and make its way through the streets of London, ending up outside the Indian High Commission, according to reports.Few UK elected representatives of Indian origin have moved the London administration to prevent this March.London mayor Sadiq Khan going on defensive has called on organisers to cancel proposed demonstration. Khan wrote to Navin Shah, member of the London Assembly, to “absolutely condemn” the protest plan “on the auspicious day of Diwali,” and called on organisers to cancel it.Khan said, “This march will only deepen divisions at a time when Londoners need to come together…I understand why many British Indians are so deeply concerned. Many have felt deeply threatened and worried since the previous protests”.“As mayor, I will continue to do all I can to extend the hand of friendship to Londoners of Indian origin – who continue to make such an incredible contribution to our city. I want to ensure they always feel respected, valued and made to feel safe in London, and that London remains a welcoming place to people from India and around the world."The August 15 incident was raised at the level of Prime Minister.
