The first group of asylum seekers due to be housed on the Bibby Stockholm barge in Portland, Dorset, have been taken onboard. Buses were seen arriving at Portland on Monday morning as activists gathered at the entrance with “welcome” signs. About 50 asylum seekers are expected on Monday. The UK government wants to use barges and former military bases to accommodate some asylum seekers after the cost of housing them in hotels soared to £1.9bn pounds last year. Their arrival came amid confusion over the government’s immigration policies at the start of Rishi Sunak’s “small boats week”, during which the government is planning a series of eye-catching announcements. A Home Office minister indicated that up to 500 asylum seekers could be onboard by the end of the week. But No 10 appeared to suggest that the minister had misspoken. The same minister indicated that the Home Office was examining proposals to send asylum seekers to a UK territory in the south Atlantic. However, Whitehall sources said the proposal was not being pursued. The Bibby Stockholm was docked off the Dorset coast nearly three weeks ago and had been empty since due to health and safety concerns. The minister for safeguarding, Sarah Dines, told BBC Radio 4’s Today programme that while only a small number of asylum seekers were expected to be housed on the barge at first, it could increase rapidly to its capacity of about 500. Pressed on whether all of them could be onboard by the end of the week, Dines said: “Yes, quite possibly it will be 500. We are hoping.” She said the increase in the number of people on the ship would be gradual, despite concerns from the Fire Brigades Union that the vessel “is a deathtrap”. Later, the prime minister’s official spokesperson said: “Numbers will increase over time as you would expect for any new asylum facility. My understanding is that the Bibby Stockholm has an upward capacity of 500. We are looking to [reach] that number over time – I don’t think we are aiming to do it by the weekend.” Dines also claimed that ministers were “looking at everything” when asked about headlines in national newspapers claiming the government was looking again at sending asylum seekers to Ascension Island. Whitehall sources have indicated the plans are not being pursued. The prime minister’s official spokesperson would not comment on “speculation”. Ministers have repeatedly said the barge will be better value for British taxpayers and more manageable for local communities – a claim challenged by refugee charities. There has been local opposition to the plan because of concerns about the asylum seekers’ welfare, as well as the potential impact on local services. The refugee charity Care4Calais said it had stopped 20 people from being forced to board the barge so far, with referrals coming in from hotels by the hour. “None of the asylum seekers we are supporting have gone to the Bibby Stockholm today as legal representatives have had their transfers cancelled,” Steve Smith, the charity’s CEO, said. “Among our clients are people who are disabled, who have survived torture and modern slavery and who have had traumatic experiences at sea. To house any human being in a ‘quasi floating prison’ like the Bibby Stockholm is inhumane. To try and do so to this group of people is unbelievably cruel.” More than 15,000 asylum seekers have arrived in the UK so far this year after crossing the Channel, official figures show. On Friday and Saturday 339 people made the journey after an eight-day hiatus amid poor weather conditions at sea, taking the provisional total for 2023 to date to 15,071. Amnesty International UK condemned using the barge to house asylum seekers. Steve Valdez-Symonds, the charity’s refugee and migrant rights director, said: “It seems there’s nothing this government won’t do to make people seeking asylum feel unwelcome and unsafe in this country. “Reminiscent of the prison hulks from the Victorian era, the Bibby Stockholm is an utterly shameful way to house people who’ve fled terror, conflict and persecution. Housing people on a floating barge is likely to be re-traumatising and there should be major concerns about confining each person to living quarters the typical size of a car parking space.” The government hopes the use of the barge and former military bases to house asylum seekers will reduce the cost of hotel bills.
