Who is Joseph Gregory Hallett (King John III)?

"There is a new King. His name is Joseph Gregory Hallett, Greg to his friends, and he says he has a legitimate claim to the throne of England – with all that this implies.
Indeed, he has lodged his official claim, with supporting documentation, with the Queen, the Prime Minister, the Pope, Presidents of US and Russia and other world leaders. So far, it seems, nobody has disputed his claim."

"A bizarre story about a man laying claim to the throne of England is seeing a surge in popularity amongst conspiracy theorists this week, particularly with the fringe right-wing group QAnon. A man by the name of Joseph Gregory Hallett (referred to by some as King John III), who originally submitted a 34-page affidavit as his Statement of Claim to British Common Law Courts in April, claims that the ‘illegitimate conception of King George V’ left a bloodline of ‘flat lie royals’ on the throne since 1840. Hallett believes the throne is now rightfully his."
