Any assumptions around the 800th anniversary celebrations of Magna Carta are bound to be shaken at Greenwich Theatre when the country’s best-known historian David Starkey talks on the subject and engages the audience in a question-and-answer session next week.

The Cambridge-educated grammar school boy, well-known for his caustic comments on TV and Radio 4’s Moral Maze, declares that the famous charter of 1215 was not the result of “some airy-fairy principles but founded on sensible people doing deals”.

His talking heads session at the theatre on Thursday, October 29, is the third of four after Germaine Greer and concert pianist James Rhodes, and concludes with Ruby Wax on Sunday, November 8.
