Shortly after landing in New Delhi to attend the 18th G20 Summit, the United Kingdom Prime Minister Rishi Sunak said that his country has been?"working closely with India to tackle Khalistani extremism."

What did Sunak say?

Stressing on the fact that the UK would not accept any form of violence he said,"?This (the Khalistani issue) is a really important question... let me just say, unequivocally, no form of extremism or violence like that is acceptable in the UK. And that is why we are working very closely with the Indian government to tackle 'PKE' (pro-Khalistan extremism)."?

"Our Security Minister was recently in India... we have groups working together to share intelligence so we can root out this kind of violent extremism. It's not right and I won't tolerate it in the UK."

Earlier, the UK security minister, Tom Tugendhat, visited Delhi last month and vowed to ensure the security of Indian diplomatic staff in London.

He said the British government is aware of India's concerns and stressed that "any attempt to radicalise people in the UK will be dealt with by the authorities".

Pro-Khalistan violence in United Kingdom

In March, pro-Khalistan elements shouting separatist slogans attacked the Indian High Commission in London and pulled down the national flag from a pole in front of the building. This was a day after police in Punjab launched an intensive manhunt for radical preacher Amritpal Singh.

The attack was decried by the UK's Business and Trade Minister as a "disgrace".
