April 27 will mark the 72nd birthday of British businessman and father of three Ryan Cornelius, but he won’t be celebrating the occasion with his loving wife or three children.

Instead, he’ll be languishing in a six-man cell in the middle of a high-security desert prison in Dubai, where the UN says he is being detained arbitrarily and unlawfully.

Ryan’s family will wish him happy birthday over the phone – the only realm where their insurmountable bond has been able to exist for what feels like a lifetime.

Arrested in 2008, Ryan was accused of defrauding the Dubai Islamic Bank (DIB) – a charge he vehemently denies – and was subsequently handed a 10-year sentence, extended by 20 years in 2018.

His release date is now May 2038, when he will be 84 years old, but his family are terrified he won’t live to see his day of freedom and will instead perish in prison.

‘Ryan is a positive and strong person, but I can tell every day now that so much of him is dying,’ his tearful wife Heather tells the Daily Mail in the days leading up to his birthday – coinciding with the 18-year anniversary of him being trapped in Dubai.

‘The hope is not there – I can’t hear it in his voice. Seventy-two is just a number, but how much longer does he have to stay in there? The absolute stress and horror of it hits me every single day, and every night I wake up in a sweat, thinking: How on earth are we going to get Ryan out?’

The family and human rights campaigners are now placing blame for this 'abject failure' of justice onto the shoulders of the UK Government – for prioritising its economic relationship with the UAE at the expense of the life and freedom of a British citizen.

The hell of Ryan’s absence, once earth-shatteringly shocking, has become baked into the family’s daily reality: he’s still their passionate, hilarious, fiercely loyal father, but from thousands of miles away in Al Awir Central Prison.

When he was first detained, Ryan’s children were 18, 16 and six. Now, they are all fully fledged adults, embarking on completely unrecognisable lives to the ones they led when their father was still at home.

Nothing will bring back those missed rugby matches, lost Christmas days or his youngest child's 18th birthday – fleeting memories of precious family life which Ryan could only imagine from behind bars.

In prison, his physical health is dwindling: Ryan has had Covid twice, is suffering with high blood pressure, cholesterol, and borderline diabetes, and his tuberculosis went untreated for 18 months.

Following his arrest, the DIB seized all of his family’s assets – including several properties in London – leaving Heather homeless and forced to rely on the kindness of relatives to make sure she had a roof over her head.

'We have literally lost absolutely everything that Ryan worked all his life very, very hard to keep up and maintain. It was a family, and were left homeless and having nothing,' she says.

Despite her own life turning upside down, it’s the thought of Ryan wasting away in prison that is always at the forefront of her mind.

‘I don't think he can survive much longer,’ she tells the Daily Mail.

‘It's just really difficult to believe that that is happening, that he's still in jail, and this massive abuse of human rights continues. We feel so helpless, and hope is all we have, but we're beginning to lose that as well.’

Heather met Ryan when she was 17. The couple were both born to British parents in Zambia (which at the time was Northern Rhodesia, a British colony) and ran into each other at the rugby club, where Ryan was a talented player.

It was his sense of humour and zest for life that made Heather fall in love.

‘I would never have wanted to be with anybody else, other than Ryan, because he is such fun,’ she says.

‘I can talk to him, and we can laugh, but not that much anymore, because it's so difficult to grasp something to talk about that is not this huge stress hanging over us.’

Once married, the pair moved to Saudi Arabia, where Ryan built and sold a hugely successful engineering company.

At the time of his arrest, he was investing in property – a marina in Bahrain, an oil refinery in Pakistan – and working on a luxury development in the Dubai desert called the Plantation.

The Cornelius family lived an enviable life in Bahrain, complete with a personal pool, gardens and a boat, enjoying the lifestyle that was a product of Ryan’s work in the UAE. The Gulf was booming, credit was cheap, and opportunities abounded for the entrepreneur.

‘Every Friday we’d go to an island, fish, barbecue and swim. Ryan was driven – he worked very hard and travelled a fair amount but when he was home he was the fun dad, the brilliant dad,’ Heather told the Daily Mail in a previous interview.

But as the world finance bubble began to deflate in 2008, the once-booming Dubai – a desert city built on debt – was instantly devastated.

A few years earlier, in 2006, saw the death of Dubai’s ruler, Sheikh Maktoum bin Rashid Al Maktoum. He was succeeded by his brother, Mohammed bin Rashid Al Maktoum, who made new appointments.

In 2008, he handed the position of chairman of DIB to his most trusted lieutenant, Mohammed Al Shaibani (the person found by a High Court judge to have been 'closely involved' in the kidnapping of the ruler’s daughter, Shamsa, when she sought to break free from Dubai in 2000).

Shaibani is also the director general of the Dubai ruler’s court, and sits on the board of Dubai’s four largest property companies.

After the financial crash, the DIB, which was providing $500million of credit to Ryan’s Plantation project, quickly called in the loan. Even then, there seemed no reason to panic. Ryan negotiated a repayment schedule and the Plantation project pressed ahead, valued by two independent bodies at more than $1 billion.

That all changed on May 21, 2008, when Ryan landed in Dubai on a flight from Pakistan, intending only to change planes to get home to Bahrain.

He was arrested, handcuffed, covered with a hood and driven to police headquarters for harsh interrogation, where he was asked to sign a document in Arabic that he couldn’t read.

For over six weeks, he was held in solitary confinement, during which he was given 15 days to repay the outstanding balance of the $500million loan.

He was denied bail, and the sudden seizure of all his assets commenced – plunging his family into into uncertainty and chaos.

Charged with fraud, he went to trial in 2010, but the judge threw out the case for a lack of evidence.

That would only bring momentary relief to Ryan, however, because a new judge was swiftly installed, and the charge was changed to ‘theft from a public body’, thereby re-classifying DIB as a state entity and the debt as theft.

He was sentenced to 10 years imprisonment, repayment of the outstanding balance, and another $500million fine.

In 2018, he was ushered without warning from his cell into a judge's office, where he was handed the shattering news that his sentence had been extended by another 20 years at the request of the bank.

The extension was secured through the retroactive application of Dubai Law 37 – which came into force in 2009, a year after his arrest.

After considering Ryan’s case in 2022, a UN working group ruled that his trial was unfair and his imprisonment ‘arbitrary’, contravening eight separate articles of the Universal Declaration of Human Rights, to which the UAE is a signatory.

For 18 years, Ryan has been trapped in Al Awir Central Prison on the outskirts of Dubai, where UN human rights officials allege prisoners are subjected to torture including beatings, forced standing, and threats to rape or kill.

There, he has experienced ‘gross neglect’, his brother-in-law Chris Pagett OBE, an ex-foreign office official, tells the Daily Mail.

‘They can go for a couple of weeks without being allowed to go outside… and they're only allowed to go outside for about an hour,’ says Heather.

‘Living under the stress of the lights on all the time, being counted and shouted at with people who you don't feel very comfortable with – that amount of stress, all the time, cannot be good for your health.’

She says he’s served fried chicken every day, with no fresh vegetables or fruit in sight, and has broken out with rashes probably due to a weakened immune system.

He desperately needs a lot of dental work, but that's been put on hold too.

‘He's had to have about four teeth extracted. We're just getting no treatment for it and he was treating himself, using Dettol to try and fight the infection,’ Chris says.

The family's fears for his wellbeing have only escalated since the US-Israeli war on Iran began on February 28.

'Ryan can hear the explosions, and a number of times I have heard things falling on the prison roof,' Chris says. 'He doesn't actually know what's going on, because there's no accurate news reporting in Dubai, but we're hearing the facts that we do out here, and that obviously adds an extra layer of worry on top of everything.'

The case has been picked up by the Global Magnitsky Justice Campaign, founded by Bill Browder, the financier and critic of state-led human rights abuses, who believes the British Government is largely responsible for Ryan’s 18-year ordeal.

‘This is a national shame of the United Kingdom: how badly we treat our falsely detained citizens, and how meekly and weakly we advocate to get them out,’ he tells the Daily Mail, calling the situation an 'abject failure' of justice.

‘Government after government in Britain values UAE money in the UK more than they value the freedom of falsely detained British citizens.’

He compares Britain unfavourably with most Western countries, from the US and Ireland to France and Italy – where leaders are prepared to ‘take the gloves off when their citizens get arrested and give these people a black eye to get their citizens out’.

‘You’re in a much worse position as a British person being arrested in Dubai or anywhere else, because the Government does very little to get out our citizens,’ he says.

From Chris’s perspective, the Foreign Office did nothing for the first 15 years of Ryan’s detainment, until the UN published its ruling in 2022, forcing politicians to wake up.

‘The British Government was just embarrassed by this case and didn’t want to know, because this case was something that threatened its attempts to have a closer financial relationship with the UAE,’ he says.

‘We have sanctions on the statute book designed to protect British citizens from this kind of gross abuse of human rights. They won't use them. They'd rather just raise the case every six months and claim that they're doing something useful.’

The family had a meeting with Foreign Secretary Yvette Cooper in January, but hasn’t heard any updates since.

In the UAE, there are three annual windows for clemency prisoner releases: at Ramadan, Eid al-Adha and the National Day.

Since January 2023, a family plea for clemency – written by Ryan's youngest son, Josh – has been submitted at each of these occasions to the UAE, under an FCDO covering letter. Each time, they have been manifestly ignored by the Ruler of Dubai.

The family have tried everything, from organising an open letter signed by 146 British parliamentarians, urging Dubai to show clemency, to even taking the case to the European Parliament, which voted overwhelmingly – 511 votes to 50 – in favour of a resolution calling for his immediate release last July.

The state of near-constant upheaval in British politics hasn’t helped matters. The family felt a glimmer of hope when David Cameron returned to government as Foreign Secretary in November 2023 – finally giving them a personal hearing.

‘He was this sharp, focused, operational character,’ Chris says. ‘We clearly felt we were talking to somebody who was going to make it a personal mission to do something about this.’

But when the Conservatives lost the 2024 general election, the family was back to square one, having to fight for face to face meetings with cabinet ministers.

In all the years that Ryan has been detained, nothing has worked, leaving the family disillusioned and desperate for the Foreign Office to finally offer more than a cover letter – but a forceful demand for the father’s imminent return.

As well as taking all his properties, the bank seized the Plantation development Ryan was working on, which is now called the Acres and would be worth more than $3billion on the basis of advertised villa prices.

That valuation after the land has been developed is more than double the amount of the businessman's outstanding restructured loan from the DIB.

For Browder, there’s clearly ‘somebody senior in the Dubai government that doesn't want any questions asked about how they got this land. And obviously, they got this land because they seized all of his assets and they threw him in prison’.

‘There’s $3billion of future revenue that could be jeopardised if all of a sudden Ryan brought into question what happened,’ he added, hence the authorities landing him with a ‘sentence that would be longer than a sentence they would give a murderer’.

He compared Ryan’s case to raider attacks in Russia – where corrupt officials weaponise the judiciary ‘as a way of transferring lucrative properties from a person who owned them, to the person who has control of the law enforcement and detention system’.

That’s why he warns wealthy foreigners against resettling in the UAE to launch their property empires, because the risk could be their life.

‘Whenever you go to a country that doesn't have a real rule of law, and you're in business with people and somebody is due to make a lot of money, there's a big incentive to misuse the legal system to reallocate, or take away, all the money that one person's going to make towards the person who has the local connections or the ability to arrest that person.

‘I think that Dubai is a place that's un-investable for that reason,’ he says, calling Cornelius’s fate ‘a trumped-up case… a shakedown to seize his business’.

But Ryan isn't at all interested in taking the UAE authorities to court, his family says – emphasising that all he's focused on is being able to spend the last years of his life with his loved ones.

The fact that he is about to spend his 72nd birthday in jail is in itself in contravention of the UAE constitution – which stipulates that prisoners should not be held beyond the age of 70.

While Ryan hasn't been present in the flesh for so many of his children's milestones, his daily calls with Heather ensure he doesn't miss a beat of their lives.

'They all have such a lot of Ryan's character,' she says. 'They all have a great sense of humour, and they all have strong beliefs in things, and they're loyal. They're really, really loyal. They're kind, they love to have fun.

'Those are the things I fell in love with Ryan about.' 

Josh takes after his father in that he's a talented rugby player, and Heather makes sure to deliver her husband a running commentary on all his games from the touchline – allowing Ryan to take part in his child's life from the prison phone. 

'There's not a single thing that any of us do that we don't tell Ryan about. I am relating life to him every day, telling him exactly how the children react to things, what they say, what fun they have, what they worry about,' Heather says.

But still, there's no escaping the gaping hole in all of their lives. 

'When it's Christmas and birthdays, we all pretend to be happy. But there's always this huge missing part. 

'We all just really desperately want Ryan home, and it's the British Foreign Office which needs to really step in and help, because they are the ones preventing him from coming out of jail.'

A spokesperson for the UAE government has previously said that all due processes were followed during Ryan's trial and that his sentence was lawfully extended in line with UAE law. They added that all prisoners receive medical care as required.

'The UAE judicial system is independent and equitable, and guarantees the mandatory presence of a translator at all stages, the right to seek a lawyer at all stages, the provision of a lawyer at the state’s expense if the defendant cannot appoint legal counsel, and the right to appeal,' they said.

The Daily Mail contacted the Foreign Office for comment.
