A misquote.

Yet another case of BBC bias on display here:

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.
