Ian Hislop continues his investigation into the confused and conflicting history of the patron saints of Britain and Ireland. How did a Palestinian fisherman become the patron saint of a land he'd never even heard of? Have the Scots got the wrong man? Ian Hislop pieces together a rather unsaintly tale of how Andrew posthumously elbowed out his rivals to the title only to be challenged in later years by a Romantic drunk, a poet ... and Mel Gibson.
