Amazon’s television service is showing films by prominent conspiracy theorists claiming that governments are controlled by human-reptilian hybrids and that global elites secretly plan to exterminate most of the world’s population.

The digital giant is spending billions on big budget dramas and sports rights to colonise the living room with Amazon Prime Video.

But as concern over online misinformation mounts The Sunday Telegraph can reveal it is also propagating the bizarre fantasies of Alex Jones and David Icke.

Mr Jones is a leading figure in the so-called US alt-right, known for his paranoid anti-government rants online.

He is being sued by the parents of children murdered in the Sandy Hook school shooting after claiming the massacre of 20 six and seven-year-olds by a mentally ill young man was staged as a “false flag” to help impose gun control.

In one of half a dozen feature-length films on Amazon Prime Video Mr Jones claims that the Obama administration was backed by a New World Order to “attempt to con the American people into accepting global slavery”.

Mr Jones has been described by the Anti-Defamation league, a US Jewish group, has highlighted his rants against jews and the “Jewish mafia. He denies anti-semitism.
