The major boost for alien hunters can be exclusively revealed by Express.co.uk on World UFO Day, which campaigners are using to call for the release of all such records globally.
UFO researchers, backed by House of Lords peer, have been fighting for the release of 18 top secret Ministry of Defence (MoD) files about UFO sightings from more than 30 years ago.
The Government faced claims of a cover-up from conspiracy theorists when their release was stalled at the end of 2013.
In his Parliamentary question, Lord Black asked: “In relation to the 18 Ministry of Defence files on unidentified aerial phenomena (UAP) that have yet to be released to the public, what is the originating division of the file reference M9/18; what is the remit of that division in relation to UAP; and what is their latest estimate of when the 18 files will be passed to the National Archives, and then released to the public.”
Defence Minister Earl Howe replied: “The originating branch of file reference MO9/18 relates to ministers’ private offices. The latest estimate of when the 18 files will be delivered to the National Archives is before March 2016.
“The National Archives will make the necessary judgement about when they release these files to the public.”
A number of older UFO files held by the UK government have already been released, including details of sightings by officials and police.
Nick Pope, who used to investigate the existence of UFOs for the MoD, said the files should contain some fascinating sightings.
However, referring to what is often called the most famous UFO claim in history – sparked by claims an alien spaceship crashed in New Mexico, US, in 1947 – Mr Pope added the soon-to-be-released files are probably not a “UK Roswell-style UFO in a hangar style cover up”.
When the release of the files were stalled in 2014, which the MoD blamed on “additional processing requirements”, Mr Pope sympathised with alien researchers.
He said at the time: “This massive delay will have conspiracy theorists up in arms. It looks like the MoD is stalling.
