John Enoch Powell (1912-1998) was a British politician who was elected to the House of Commons first as a Conservative MP (1950-1974), and later as an Ulster Unionist MP (1974-1987). He served as Minister of Health under Harold Macmillan.
Enoch Powell is infamous for a speech delivered in April 1968 in which he condemned Commonwealth immigration to Britain. His stance was perceived by many to be deeply racist, and the speech earned itself the title 'the Rivers of Blood' speech. The actual words he used were, 'As I look ahead, I am filled with foreboding; like the Roman, I seem to see the River Tiber foaming with much blood'.
