The family of a Briton killed in the 9/11 terror attacks is controversially claiming that the Twin Towers were brought down by internal explosions and not by hijacked aircraft crashing into them.
Relatives of 31-year-old Geoff Campbell are challenging the accepted version of events and demanding a new inquest.
The Campbell family, backed by a scientific team, make the astonishing claim that the World Trade Center towers in New York were laced with explosives, provoking their collapse and causing Mr Campbell's death alongside more than 2,600 others on September 11, 2001.
A 3,000-page dossier detailing this extraordinary allegation is to be handed this morning to the Government's top legal adviser, acting Attorney General Michael Ellis.
It insists 'significant evidence' went unheard at the 2013 London inquest of Mr Campbell and nine other Britons who perished in the atrocity.
The inquest ruled the ten had been 'unlawfully killed' in an 'act of terrorism' by Al Qaeda flying aircraft into the towers and causing their 'total destruction' – a decision in keeping with official accounts.
The conspiracy theory that the towers were downed in a controlled explosion was first raised in the immediate aftermath of the attacks but has been dismissed by several expert studies.

Puzzling inconsistencies that the Campbells' dossier highlights:
The Cambells' dossier notes several major inconsistencies in the official narrative:
The demand to the Attorney General is expected to trigger permission for the family to apply to the High Court for a fresh inquest. Risk analyst Mr Campbell was working on the North Tower's 106th floor when he died.
His older brother Matt Campbell, told the Mail yesterday: 'I believe there has been a cover-up. We have scientifically and forensically-backed evidence that the official narrative surrounding the Twin Towers collapse on 9/11 is wrong.'
The Campbells' demand is being made under Section 13 of the UK Coroners Act 1988 which allows an inquest to be re-run in the 'interests of justice' if substantial new evidence comes to light.
The Section 13 rule was used in 2016 to re-open the inquiry into the deaths of 97 fans in the Hillsborough football stadium disaster.
The family, including Mr Campbell's parents and his American former fiancée Caroline Burbank, say their evidence challenges official US reports that fires caused by fuel from the crashed jets brought down the towers.
But the dossier says this makes no scientific sense: most steel does not melt until it reaches around 2,800f (1,537c), and open fires of jet fuel — such as those in the Twin Towers inferno — cannot burn hotter than 1,700f (926c).
Nine respected scientists have also published peer-reviewed research showing that dust from the destroyed Twin Towers contained microscopic remnants of nano-thermite explosives, which can be tailored for use in controlled demolitions.
There are other puzzling inconsistencies that the Campbells' dossier highlights for the first time about the destruction of the two towers.
The official narrative of the North Tower's collapse is that it went 'essentially into free fall', the upper section of the building accelerating through the lower floors at close to the rate of gravity, completely dismembering steel frames and pulverising thick concrete to a fine powder.
But this would have been impossible, say experts at the campaign group A&E.
They cite Newton's third law of motion, which states that for every action there is an equal and opposite reaction.
In other words, the absence of deceleration in the 'free fall' is apparent proof that another force — explosives — had already destroyed the lower part of the building, allowing the upper section to plunge down through it at an increasingly fast pace.
There are also those compelling personal tales of explosions at the site.
In oral histories of 9/11 provided by New York Fire Department staff, almost a quarter describe seeing flashes and hearing bangs and booms in both the Twin Towers before they fell.
One fire officer, Frank Campagna, said of the North Tower: 'I looked back. You could see three explosions and then the whole thing coming down.'
His testimony is endorsed by hundreds of other workers and police officers at the World Trade Centre site that day who insist they saw explosions in the basement and lobby.
The Campbell family make the astonishing claim that the World Trade Center towers in New York were laced with explosives, provoking their collapse and causing Mr Campbell's death alongside more than 2,600 others on September 11, 2001
The evidence to the Attorney General, which will go to any new inquest, also contains witness accounts of explosions before the Twin Towers were struck.
According to the Campbells' dossier, seismographic recordings, measuring sudden ground movements, were picked up 12miles from the North Tower, 15 seconds earlier than 8.46.40 am, the time a hijacked American Airlines jet struck the building.
For a new inquest to be allowed, the family merely need to show that evidence not considered at the first inquest may lead to a different verdict.
Father of three Matt Campbell added last night: 'We want justice for Geoff who was a brilliant analyst, had just got engaged, and had his whole life ahead of him.'
Conspiracy theorists claim 9/11 was fabricated to provide a pretext for America to start the so-called War on Terror.
But theoretical physicist Mr Campbell insisted: 'This family are not conspiracy theorists. We only want the truth, and justice for Geoff.'
Spike Lee is re-editing his HBO series on 9/11 to INCLUDE conspiracy theories after admitting he believes WTC 7 was brought down by explosives
Spike Lee announced that he is re-editing the final episode of his documentary on 9/11 after backlash he faced for featuring conspiracy theorists
Director Spike Lee announced he is re-editing the final episode of his 9/11 documentary after admitting he believes a conspiracy theory that the attacks were caused by a controlled demolition.
'I'm Back In The Editing Room And Looking At The Eighth And Final Chapter Of NYC EPICENTERS 9/11➔2021½. I Respectfully Ask You To Hold Your Judgment Until You See The FINAL CUT,' read a statement Lee posted on an HBO exclusive platform.
Also included were views of experts who have closely studied the 9/11 attacks, including S. Shyam Sunder, who led a lengthy investigation for the National Institute of Standards and Technology, and who has debunked conspiracy theories about the terror attacks.
Lee's decision to make final edits and to release previews featuring scientists seem to be efforts of damage control. The about-face comes after rising criticism that the documentary didn't offer an even balance of arguments, and even sided with conspiracy theorists by giving them a platform just weeks ahead of the 20th anniversary of the atrocity.
The last episode, which will air on the 20th anniversary of the attacks, includes several members of 'Architects and Engineers for 9/11 Truth' - a group that has suggested the United States government was involved with the collapse of the World Trade Center on September 11, 2001.
In an interview with The New York Times on Monday, Lee admitted he believed the that 7 World Trade Center skyscraper could have not collapsed because of the heat, and rather seemed like an internal demolition.
The original WTC 7 was a 42 story building constructed in 1987, which was filmed tumbling to the ground after the Twin Towers collapsed. Some angles showed the seemingly undamaged tower collapse onto its own footprint sparked, which controlled demolition claims. But footage from the other side of the building shows a huge gash caused by falling debris.
World Trade Center 7 included a New York bureau for the CIA, sparking further conspiracies of an inside job. But units in the building were available for anyone to rent, and experts insist there was no government plot to destroy it.
Critics have argued that conspiracy theorists' and scientists' arguments should not be presented to the public as if they were in the same realm of expertise.

Jeremy Stahl, editor for Slate, wrote in an article for the magazine: 'In terms of conveying facts, this is a bit like presenting Covid-19 vaccine skeptics in a debate alongside Anthony Fauci, or Holocaust deniers alongside the Simon Wiesenthal Center, or a clique of climate change skeptics alongside the authors of the United Nations IPCC report'
But Lee has defended the content of his series, saying that viewers are entitled to hear arguments from both sides.
'My approach is put the information in the movie and let people decide for themselves. I respect the intelligence of the audience,' he said.
The documentary also includes interviews with New York politicians like Senator Chuck Schumer and Mayor Bill de Blasio, along with various health care workers, firefighters and activists.
He said the New York Police Department declined to be interviewed in his documentary due to his views on police.
When Times reporter Reggie Ugwu asked Lee about the group's inclusion in the documentary series, Lee responded: 'I mean I got questions, and I hope that maybe the legacy of this documentary is that Congress holds a hearing, a congressional hearing, about 9/11.'
Ugwu then asked Lee if he believes the 'official explanations' for the World Trade Center collapse on September 11, to which Lee claimed: 'The amount of heat that it takes to make steel melt, that temperature's not reached.
He was discussing his new documentary series New York City Epicenters 9/11 to 2021 1/2, which includes interviews with a conspiracy theory group
'And then the juxtaposition of the way Building 7 fell to the ground - when you put it next to other building collapses that were demolitions, it's like you're looking at the same thing,' Lee said in the interview.
At that point, Ugwu asked Lee why he believes in 9/11 conspiracies but does not support conspiracy theories about vaccines or the 2020 election, to which Lee quipped: 'People are going to think what they think, regardless.
'I'm not dancing around your question,' he said. 'People are going to think what they think.'
He noted: 'People have called me a racist for Do the Right Thing. People said in Mo' Better Blues, I was anti-Semitic, She's Gotta Have It that was misogynist.
'People are just going to think what they think,' Lee said. 'And you know what? I'm still here, going on four decades of filmmaking.'
The controlled demolition theory has been around since the immediate aftermath of the 9/11 terror attacks, when Building 7 was hit by debris from the Twin Towers and was damaged by fires, which burned for seven hours until it was completely destroyed at about 5:20 p.m.
Some proponents of the theory suggest the building was demolished because it may have served as an operational center for the demolition of the Twin Towers, while others suggest that government insiders may have wanted to destroy files about corporate fraud.
Loose Change film producer Dylan Avery once said he thought the destruction of the building was suspicious because it housed a CIA office, an outpost of the Secret Service, the Securities and Exchange Commission and the city's emergency command center.
But United States Special Operations Command has said anyone could have rented space in the building.
The National Institute of Standards and Technology also investigated the claims and 'found no corroborating evidence for alternative hypotheses suggesting that the World Trade enter towers were brought down by controlled demolition using explosives planted prior to September 11, 2001.'
'Instead, photographs and videos from several angles clearly show that the collapse initiated at the fire and impact floors, and that the collapse progressed from initiating floors downward until the dust clouds obscured the view.'
Lee has been a top Democratic donor and has campaigned for far left politicians over the past few years.
In 2012, FOX reports, he hosted Obama in a fundraiser at his Manhattan home, then in 2016, he campaigned for Vermont Senator Bernie Sanders ahead of the primaries, even appearing in a radio ad for the senator.
Then in 2019, Lee hosted a sold-out fundraiser for now vice president Kamala Harris in Martha's Vineyard.
He has said the NYPD declined to be interviewed in his new documentary due to his unflattering portrayal of the police in the past.
'The only people who said no was NYPD,' Lee said in the interview. 'They don't look good in this.
'And that footage of police officers assaulting Black Lives Matter protesters in 2020 does not lie. They were cracking heads.'
