India has “disengaged” from trade talks with Britain after accusing it of failing to condemn the Sikh extremist group that attacked the Indian High Commission in London last month, The Times reported on Monday, citing British government sources.

The incident occurred on March 19, when protesters carrying Khalistan banners staged a rally at the High Commission and took down an Indian flag from the building’s first-floor balcony to denounce the recent police action in Punjab.

“Indians don’t want to talk about trade until they have a public demonstration of condemnation of Khalistan extremism in the UK,” a Whitehall source told The Times.

India had said last month that it expected to see action against the perpetrators of vandalism in its missions abroad and hoped that host governments would prosecute those involved in these incidents rather than offer guarantees. At the weekly briefing on March 24, Foreign Ministry spokesman Arindam Bagchi also said that New Delhi hopes that host governments will take measures to prevent the recurrence of such incidents.

Indian missions in London, British Columbia and San Francisco were allegedly vandalized by pro-Khalistan activists following police action against radical preacher Amritpal Singh in Punjab.

On March 19, supporters of the Khalistan movement lowered the Indian flag at the country’s high commission in London and smashed the building’s window in a show of anger against the move to arrest Amritpal Singh, who remains elusive.

India’s foreign minister denounced the incident and summoned the UK’s deputy high commissioner in New Delhi to protest what he called the breach of security at the embassy in London.

On March 22, police removed temporary security barricades outside the British High Commission in New Delhi, the PTI news agency reported.

Supporters of the Khalistan movement also vandalized the Indian Consulate in San Francisco on March 20.
