David Ervine of the Progessive Unionist Party, aligned to the Ulster Volunteer Force, said the warning signs had been there - Protestant discontent was a "cauldron that overflowed".
Now, I saw the bastard Ervine saying this on TV, and that is not what he said. What he actually said that this cauldron of his had done was "overflown". I remember, because I laughed at this profoundly ugly man trying to appear righteously angry and instead giving me a mental image of a winged cauldron soaring over Belfast an image which, for some reason, fails to make me angry at Whitehall.
OK, so it's an instance of the BBC's bias against dodgy English. It's still bias.
