The final cross word

I'm finishing off the current series of acrostics with this article which The Guardian published in July 2011, just after the closure of The News Of The World. It features that paper's final crossword where several hidden messages and keywords were revealed once the puzzle was solved.

The article includes several links to other acrostics, some of which I've mentioned in recent posts.

So, did you spot the hidden message? As the caption says, the message they've 'left'?

No?

Well, I'm not going to spell it out.
