Prince Philip was meant to meet an alien called ‘Janus’ at a flat in Chelsea, a new documentary has rather casually claimed.

The King of UFOs, which will be streaming on Amazon and Tubi on September 20, described how the late Duke of Edinburgh’s engineering background made him passionate about all things extraterrestrial.

So meeting an alien was an offer that the husband of Queen Elizabeth struggled to refuse, apparently.

The film’s director, Mark Christopher Lee, told Metro.co.uk that the meeting was arranged by the Prince’s top aide at the time, Sir Peter Horsley.

‘Horsley actually met this Janus entity in a flat in Chelsea in 1954 – he claimed that it had an ethereal otherworldly quality and it could read his mind and extract information about flying saucers,’ Lee said.

The pair were pencilled in to meet at a flat along Smith Street, a small residential road about a 10-minute walk away from what is now Sloane Square Tube station, on a ‘winter’s evening’.

‘Horsley wanted Phillip to meet with this Janus as Janus had a message to give him that the world needed saving as Philip was a man of great vision,’ Lee added.

‘Philip didn’t go to the meeting – and it’s most likely that Janus could have been a Russian spy – but Horsley stuck to his belief that Janus was not of this world.’

Horsley did mention this possible close encounter in his memoir, Sounds From Another Room, in which he described a serious ‘Mr Janus’ with an intimate knowledge of aliens that UFO experts have widely interpreted as being extraterrial.
