The "very well known person" the ICAC is referring to

The lads at the table of knowledge at the local watering hole, who are not averse to having an occasional wager, are flabbergasted that the sports agencies (aka the online betting mob) haven't framed a market on who the "very well known person" is that the ICAC is currently referring to in relation to a chain of controversial emails between that "very well known person" and a Liberal identity.

 It's possible to punt on just about every other imaginable event, so why not the identity of the "very well known person"?

For example, one agency is offering odds (see below) on who will be first to confirm by September 2015 they have been abducted by aliens.

BTW, one of the lads reckons both Clive and Alan are well over the odds in the Aliens Stakes and is real keen to have a a few bob that the "very well known person" is someone who came undone at the ICAC quite a few years ago. Could he be right?
