On 23 February 2017, Sarker and her ancestors were the subject of an episode of "Who Do You Think You Are?" shown on BBC One in which she traced them to Bengal. She learned about her family's involvement in the struggle for independence in India and one of her ancestors' connection to Gandhi. Travelling next to Bangladesh, she visited her great-grandmother's ancestral village where she discovered the story of how her family were caught up in the Bangladeshi war of independence from Pakistan in 1971.
