A dossier of files kept secret by the UK government for almost 50 years could be released after June's general election.
The documents will be published by the National Archives and are believed to contain details of sightings of UFOs over almost five decades.
And alien hunters are hoping they will reveal evidence of a cover-up of a number of high profile incidents they believe are related to extra-terrestrials, including in Rendlesham Forest in 1980, dubbed 'Britain's Roswell.'
The National Archives has previously released huge swathes of material gathered by the Ministry of Defence's (MoD) UFO Desk, thought to number in the thousands.
The files still to be published are believed to date from 1971-76, 1996-2000 and 2004.
The papers were originally meant to be released in 2013 alongside thousands of others which did see the light of day, but 18 specific documents were withheld.
