The morality campaigner Mary Whitehouse was a trigger warning long before the term was used. From the 1960s onwards she pursued the BBC over sex and swearing on television and brought private prosecutions against the publisher of Gay News and the director of Howard Brenton’s play, The Romans in Britain, for what she viewed respectively as blasphemy and gross indecency.
So, when Maxine Peake plays the Christian cultural vigilante in The Last Stand of Mrs Mary Whitehouse at the Nottingham Playhouse this week, will there be a warning about its content?
