The row over a period Bollywood epic - that no one has seen yet - continues as one rightwing Hindu extremist group said it would ask its "brothers" in the UK to burn down cinemas after British censors gave it a release date.

Protests and threats have been made against the stars and director of the film Padmavati, over what the Rajput Hindu community of Rajasthan say are historical inaccuracies and stains on the honour of the central character - a fable queen from medieval times.

India's Central Board of Film Certification returned the film's application for a rating to the director, Sanjay Leela Bhansali, and have announced the movie's release will be delayed, for how long no one is sure.

Meanwhile, Sukhdev Singh of the Karni Sena group, claiming to represent Rajput communities, said: “Every cinema screening Padmavti will be burnt to the ground.” Threatening violence in the UK, Singh said he would ask the people from the Rajput community in Britain to stage protests against the film, as there have been in India.
