Palmer Luckey, the virtual reality pioneer, left Facebook in 2017, six months after it was discovered that he had secretly funded a pro-Trump campaign group dedicated to influencing the US election through "shitposting" and "meme magic".

The 25-year-old Oculus founder now has a new venture, Anduril Industries, this time supporting Trump's immigration policies directly through the creation of a surveillance system designed to detect unauthorised crossings of the Mexican border.
