His bombshell claims come just weeks after it emerged the US Pentagon had a top-secret UFO investigation team from 2007 to 2012, that allegedly obtained “materials from UFOs”.
In December, a New York Times article revealed details of a top-secret £16 million US Pentagon study into the potential threat posed by UFOs.
The report claimed the Department of Defense (DoD) Advanced Aerospace Threat Identification Programme (AATIP) even recovered “unknown alloys” believed to have come from a UFO that had been tested and found to have properties unknown to science.
Mr Hellyer, who was a minister in the 1960s, believes top secret departments have been harvesting technology from the advanced lifeforms to develop hi-tech weaponry and aircraft, Dailystar.co.uk reports
In a recent Lazarus Effect YouTube podcast he claimed some of this groundbreaking knowledge had “most certainly” been shared with the UK.
A former US Air Force Charles James Hall, who has written about his alleged encounters with aliens at a Nevada base, reportedly told Mr Hellyer they had a hangar for a “mother ship that came into the side of a mountain on the nights of the full moon”.
Mr Hall claims the air force, back in the 1960s, had already been exchanging technological information with “tall whites”, an alleged blonde-haired human-like race of aliens, according to Hellyer.
In the podcast, Mr Hellyer, 93, said: “If the US was that far advanced in the exchange of technology in the 1960s where are they today?”
“They’ve been working on technology that they got from the aliens and not only that but the particle guns based on the work of Tesla and others.
“That is the primary purpose of the anti ballistic missile shield, the weapons are ones that can be aimed in either direction to control the situation on earth but equally, if not more important, to shoot down UFOs.
“I do believe they have developed two or three kinds of weapons that are capable of disabling and bringing down UFOs.”
Mr Hellyer has remained in Canadian politics throughout his career and is the longest serving current member of the country’s Privy Council.
His theory claims that four species of aliens have been visiting Earth for thousands of years.
Conspiracy theorists claim that a UFO was found crashed outside the New Mexico town and the remains of it have been hidden away ever since.
Since news broke of the AATIP broke there have been calls for the metal and any reports on it to be produced, but so far nothing has materialised.
