Asylum seekers brought back to the Bibby Stockholm barge in Portland, Dorset, have said they are being treated in such a way that “we despair and wish for death”. The Guardian spoke to two men in their first interview since their return to the barge on 19 October after the vessel lay empty for more than two months. The presence of deadly legionella bacteria was confirmed on board on 7 August, the same day the first group of asylum seekers arrived. The barge was evacuated four days later. The new warning comes after it emerged that one asylum seeker attempted to kill himself and is in hospital after finding out he is due to be taken to the barge on Tuesday. A man currently on the barge told the Guardian: “Government decisions are turning healthy and normal refugees into mental patients whom they then hand over to society. Here, many people were healthy and coping with OK spirits, but as a result of the dysfunctional strategies of the government, they have suffered – and continue to suffer – from various forms of serious mental distress. We are treated in such a way that we despair and wish for death.” He said that although the asylum seekers were not detained on the barge and could leave to visit the nearby town, in practice, doing so was not easy. He added: “In the barge, we have exactly the feeling of being in prison. It is true that they say that this is not a prison and you can go outside at any time, but you can only go to specific stops at certain times by bus, and this does not give me a good feeling. “Even to use the fresh air, you have to go through the inspection every time and go to the small yard with high fences and go through the X-ray machine again. And this is not good for our health. “In short, this is a prison whose prisoners are not criminals, they are people who have fled their country just to save their lives and have taken shelter here to live.” The asylum seekers raised concerns about what conditions on the barge would be like if the Home Office did fill it with about 500 asylum seekers, as officials say is the plan. Those on board said it already felt quite full with about 70 people living there. The second asylum seeker said: “The space inside the barge is very small. It feels crowded in the dining hall and the small entertainment room. It is absolutely clear to me that there will be chaos here soon. “According to my estimate, as I look at the spaces around us, the capacity of this barge is maximum 120 people, including personnel and crew. The strategy of ​​transferring refugees from hotels to barges or ships or military installations is bound to fail. “The situation here on the barge is getting worse. Does the government have a plan for shipwrecked residents? Everyone here is going mad with anxiety. It is not just the barge that floats on the water, but the plans of the government that are radically adrift.” Maddie Harris of the NGO Humans For Rights Network, which supports asylum seekers in hotels, said: “Home Office policies directly contribute to the significant deterioration of the wellbeing and mental health of so many asylum seekers in their ‘care’, with a dehumanising environment, violent anti-migrant rhetoric and isolated accommodations away from community and lacking in support.” A Home Office spokesperson said: “The Bibby Stockholm is part of the government’s pledge to reduce the use of expensive hotels and bring forward alternative accommodation options which provide a more cost-effective, sustainable and manageable system for the UK taxpayer and local communities. “The health and welfare of asylum seekers remains the utmost priority. We work continually to ensure the needs and vulnerabilities of those residing in asylum accommodation are identified and considered, including those related to mental health and trauma.” Nadia Whittome and Lloyd Russell-Moyle, the Labour MPs for Nottingham East and Brighton Kemptown respectively, will travel to Portland on Monday to meet asylum seekers accommodated on the Bibby Stockholm barge and local community members. The visit follows the home secretary, Suella Braverman, not approving a visit from the MPs to assess living conditions as they requested through parliamentary channels.
