THE BOY WITH THE TOPKNOT

BBC2, 9pm

Sathnam Sanghera was born to traditional Sikh parents and grew up in Wolverhampton. “I had a topknot until I was 14”, he says. But things have changed since then.

This 90-minute drama, starring Sacha Dhawan, is touching, funny and emotional as it follows journalist Sathnam’s real-life story. It starts as he visits his parents who are off on a trip. “Your cousin is to marry a beautiful Jat Sikh girl from Coventry,” says his mum. “Such a sensible boy.”

So when should he mention that his girlfriend (Joanna Vanderham) is someone he met at Cambridge University who’s very much non-sikh?

But while pondering his dilemma, he rifles through his parents’ suitcase, trying to solve their excess baggage problem, and learns a painful truth.
