To others he is a dubious figure deserving of scorn and ridicule.
But whatever you may think of him, David is one of the world’s most prominent conspiracy theorists and has a global following to match.
His controversial claims include that the world is run by a secret cabal of alien lizards who appear to us as well-known public figures.

So is he just another conspiracy crank? Or something else entirely?
Join me and David in the London Real studio and decide for yourself.
