Sure, the UK is harbouring terrorists against India. Tell the people anything to distract them from how badly the Indian government is doing relative to the Chinese government.
Now this ?
British intelligence agencies knew about the 7/7 Jihadis receiving terrorist training in Pakistan occupied Kashmir & yet decided not to act since they assumed that the latter were only conspiring against India, not the UK.
This fact was stated in the 7/7 investigation report
In the late 90s British Government allowed Jihadis Hafiz Saeed to visit UK to openly declare Jihad against India & collect funds for the same from British Pakistanis.
And then there is British media openly supporting terrorism against India.
