Arts news and reviews with Mark Lawson. Her Naked Skin, a new play by Rebecca Lenkiewicz, tells the story of female liberation. The advancement of women is both the subject and the object of the play, which is about to become the first work by a female dramatist to be staged in the National Theatre. In all theatres across Britain over the last century, the vast majority of scripts have been written by men. In a special programme, Mark investigates why theatre has remained such a male-dominated form.
