A British couple jailed in Iran on charges of espionage have lost an appeal against their decade-long sentences, sparking their family to call out the UK Government over claims it is 'passively managing' their case. Craig and Lindsay Foreman, from East Sussex, were handed a 10-year sentence each in February in Tehran's notorious Evin Prison after being convicted of spying, which they both deny. The family have been ruthlessly campaigning for the couple's release, however were hit by a significant blow this week after the Foreman's appeal was rejected - a decision that comes after the couple was barred from their own appeal hearing. Lindsay's son Joe called out the Government over claims the couple are 'disappearing' into a 'fundamentally unjust' system. He told the Daily Mail: 'For months, this case has been handled through a process that has produced no meaningful process and very little transparency. 'My concern now is that we are stuck in a cycle of passive management rather than active resolution. The dial needs to shift from simply monitoring the situation to applying real diplomatic urgency and pressure.'The news comes amid the couple's joint hunger strike, with Craig on day 25 and Lindsay on day 16, prompted after, Joe said, 'they ran out of ways to make their own Government act'.This has taken an additional toll on the couple's mental strength. Joe, from Folkestone, Kent, described his mother as 'defiant' but is 'understandably tested'. Lindsay and Craig Foreman (pictured), both 52, were arrested in Kerman, southern Iran, on January 3, as they embarked on a motorcycle trip around the world to Australia Joe Bennett (pictured), Lindsay's son, has been campaigning for their freedom for more than a year He continued: 'She has shown extraordinary resilience throughout this ordeal, but there is only so much any human being can endure after more than 500 days imprisoned in a foreign country under these conditions.'These are conditions which include rat-infested and overcrowded cells, as well as US-Israeli strikes and mental games, including the last-minute pulling of their entitled spousal visits within the prison.The family understand 'basic communication' between the pair is now 'heavily restricted', as they are only allowed to 'speak very briefly' and in a 'highly limited and controlled way'.Lindsay, a business coach, and Craig, a carpenter, were arrested on January 3 in Kerman, southern Iran, last year while passing through the country on a round-the-world motorcycle trip, ending in Australia.The couple set off from the UK in November 2024, having taken up motorcycling a few years earlier in memory of Lindsay's brother, Ashley, who died in a motorcycle accident in 1993.Despite having Iranian visas, a guide and an approved itinerary, the Foreman's were sentenced and imprisoned on claims they were spying for the UK and Israel.Both the couple's lawyers and the UK Government have argued their case lacks legal basis, while they were also prevented from defending themselves at a court hearing in October - leaving them to feel like they are being used as diplomatic leverage rather than being rightly convicted criminals.The family have since been left further in the dark, Joe said, after it is not known whether his mother and step-dad 'received a proper account of what was argued on their behalf' at the appeal.The couple (pictured), from East Sussex, had intended to travel from Armenia to Pakistan via Iran when they were intercepted by authorities and later charged with espionage
