An empty taxi arrived and out of it stepped Attlee.
Notes from Wikiquote
Mr Attlee is an honourable and gallant gentleman, and a faithful colleague who served his country well at the time of her greatest need. I should be obliged if you would make it clear whenever an occasion arises that I would never make such a remark about him, and that I strongly disapprove of anybody who does. | Churchill to John Colville (quoted in Nigel Rees, Sayings of the Century (1987), p. 106).
