Actress, author and activist Twinkle Khanna, has been invited to speak at The Oxford Union, the world's most prestigious debating society.

Twinkle Khanna's first book Mrs Funnybones sold over 100,000 copies, making her the highest-selling female author in India and her second book, The Legend of Lakshmi Prasad, featured a collection of short stories, debuting at number two on Amazon India’s bestseller list.

One of the stories, Salaam, Noni Appa, has been adapted for a stage production and another story about a man who invented a machine to make low-cost sanitary pads had cinematic potential, so Twinkle Khanna turned producer to develop it for the big screen.

The result is her latest endeavour, Pad Man, the world’s first feature film on menstrual hygiene, based on the life of social entrepreneur and activist Arunachalam Muruganantham, who revolutionised sanitary hygiene in rural India 20 years ago.

At The Oxford Union, Twinkle Khanna is set to explain why it is important the world knows about Pad Man’s story, the imperative need to spotlight issues relating to menstrual hygiene, tackling taboos and breaking down the stigma attached to periods globally as a means to empower girls and women worldwide, and how movies have the potential to become movements.

Twinkle Khanna is set to speak at the Oxford Union on Thursday 18 January.
