Scummy idea

Labour deputy leader Angela Rayner called Tories ‘scum’ in a speech to activists at her party’s conference. The word, derived from a 14th-century Dutch word for foam, was first recorded in the sense of an insult in Christopher Marlowe’s play Tamburlaine, written in the late 1580s. Referring to Christian slaves kept by the Turks, Tamburlain says: ‘These are the cruel pirates of Argier, that damned train, the scum of Africa.’
