Exclusive: Preet Gill says a number of Sikhs have been stopped at border, raising concerns over Delhi’s influence

British Sikhs are being stopped at airports and questioned about their attitudes towards India, a Labour MP has said, raising concerns about Delhi’s influence over British security checks.

Preet Gill, one of the most prominent Sikhs in parliament, has written to the home secretary, Yvette Cooper, to voice her concern over a number of British Sikhs who she says have been stopped and questioned at length when re-entering the UK. The questions have centred on the decades-old dispute over whether Sikhs should be granted their own homeland in south Asia.
