Millington wore his DFC ribbon on his uniform when attending the House of Commons, as was customary at the time. Many years later he fondly recalled being reprimanded by a Conservative MP who bemoaned the fact that Millington's ribbon was being incorrectly worn. Millington told the BBC, "I was approached by a Tory MP dressed in civilian clothes and with a hand in his trouser pocket. 'Your DFC ribbon is worn too wide'. He was, I think, not expecting my reaction. 'If you are talking to me as an RAF officer: stand to attention; take your hand out of your trouser pocket and address a senior officer as Sir. If you are talking to me as a fellow Member of Parliament, mind your business and bugger off.'"
