The vessel, which arrived from Italy, is due to be moved to Portland to house the migrants off the Dorset coast.

The plan has been met with criticism from local groups, refugee charities, and Conservative MP Richard Drax, who has threatened a legal case. Concerns have also been raised about pressure on health services.

However, Prime Minister Rishi Sunak defended the plan, stating that it would save taxpayer money and reduce pressure on hotels. The Home Office said that the barge would be “significantly cheaper” than hotels and would be used to house single men while they wait for their asylum claims to be processed. The barge is expected to operate for at least 18 months.

Refugee groups have called the plan “completely inadequate”, while councillors from the local area have opposed the proposals. The use of the Bibby Stockholm marks the first time migrants have been housed in a berthed vessel in the UK.

The Home Office said the Bibby Stockholm would undergo inspection, refurbishment, and maintenance in Falmouth but would not be used to house asylum seekers there. Dorset Council said it had “serious reservations” about the suitability of Portland Port as a location and remained opposed to the proposals.

Immigration Minister Robert Jenrick defended the plan, stating that the use of expensive hotels to house an “unprecedented number” of asylum seekers crossing the Channel had to end. He said there were more than 51,000 asylum seekers in hotels costing the taxpayer £6m a day.

“We are continuing to work closely with the councils and key partners to manage any impact in Falmouth and Portland and that appropriate arrangements are in place,” he added
