Lesbian love story wins Palme d'Or at Cannes

The sexually graphic lesbian love story "Blue is the Warmest Colour" on Sunday scooped the top Palme d'Or prize at the Cannes Film Festival.

French-Tunisian director Abdellatif Kechiche's three-hour film set Cannes abuzz with its explicit unsimulated sex scenes and has made a star out of one of its lead actresses Adele Exarchopoulos.

Head of the jury Steven Spielberg, announcing the prize, said the jury was this year taking the unusual step of honouring three people with the award -- Kechiche, Exarchopoulos and the other lead actress Lea Seydoux, who all went on stage to accept the accolade.
