The US President is under pressure thanks to similar disclosure promises made by the campaign of Democratic candidate for Obama’s replacement, Hillary Clinton.
Stephen Bassett, executive director of US-based Paradigm Research Group (PRG), believes that there could be a massive announcement to come.
And he says David Cameron will follow suit almost immediately after.
“This will be a reality this year and across the front pages of newspapers across the world, he told the Daily Express, adding that “ET is real”.
“The most significant news story that has ever been broken.”
“We are going to get disclosure this year. I am not sure who will win the election, but I think Obama will be the disclosure president.
“He will be looking at a Nobel Prize for making an announcement like that.
“I am 85% sure Obama will make the announcement before he leaves office and within days your Prime Minister David Cameron will follow.”
The possible revelations would come just months after Clinton told a US talk show that she was keen on transparency of information on ET and UFOs.
Campaign manager John Podesta also spoke about releasing top-secret files.
The Democratic candidate spoke out on Jimmy Kimmel Live as she leads the race against Bernie Sanders for the party’s nomination for November’s election.
She has followed in the footsteps of her husband Bill, who appeared on the show in 2014 and was asked if he ever looked into UFOs or Area 51 – a top secret airbase rumored to “back engineer” alien craft.
Bill said “sort of” but added there were no dead aliens there.
Speaking for the first time on TV about the issue, she told Kimmel: “I’m going to do it again. There’s a new name for UFOs. It’s unexplained aerial phenomena.
“That’s the new nomenclature. I would like us to go into those files and hopefully make as much of that as public as possible.
“If there’s nothing there, let’s tell people there’s nothing there. If there is something there, unless it’s a threat to national security, we ought to share it.”
