Channel 4 News' Cathy Newman is joined by the former Met murder squad's senior investigating officer Colin Sutton, the former chairman of the Intelligence and Security Committee, Kim Howells and in Germany the author and ex MI5 officer Annie Machon.
And remember, Foreign Secretary and First Secretary of State, William Hague signed a Public Interest Immunity order just before this inquest was to begin.
"Transparency needs forcing on some of these agencies," Annie Machon.
CONSPIRACY WARNING: Scotland-based Government/Home Office researcher Andrew Wallace reckons he's 'joined some dots', his words, and suggests that the fact that Gareth's laptop is still missing, the fact that Gareth had just returned from USA hacker conference, that 'if UK developed Stuxnet virus to infect Iranian nuclear power industry then both GCHQ and SIS (places where Gareth worked) would have been involved', points to a Russian or Iranian hit squad doing Gareth, via a plumbing/heating visit scenario.
But beware: Any intel group intent on a mischievous diversion in the game could weave a POLITICALLY BENEFICIAL SCENARIO around such a fertile, badly-managed and mysterious death as Gareth's. You have been warned, this game is still running.
