Here is the letter that MP Tom Watson has sent to PM David Cameron, regarding the UK elite pedo ring investigation:

Watson, apparently, is a long-standing foe of Rupert Murdoch and a co-author of "Dial M for Murdoch," which focuses on the phone-hacking scandal. So it would appear that A) this Watson guy is one of the good ones, and B) there might be some overlap between the pedo ring and other on-going British scandals.
But he grew old, this knight so bold / And upon his heart a shadow / Fell as he found / No spot on the ground / That looked like El Dorado.
