Rishi Sunak still has confidence in the home secretary and her department despite the ongoing controversy around the Bibby Stockholm, Downing Street has said.

The prime minister’s official spokesman defended the Home Office’s response to the discovery of Legionella on the barge last week, but said lessons would be learned following the incident.

Asylum seekers were removed from the barge on Friday after the bacteria was found in the vessel’s water system.

Legionella bacteria can cause a potentially deadly lung infection known as Legionnaires’ disease. It is contracted by people breathing in droplets of water containing the bacteria.

None of the migrants on the barge have shown any symptoms of the disease, according to the Home Office.

It later emerged that people spent four days on board the barge after the bacteria was discovered and before they were removed by the Home Office as a “precautionary measure”.

The discovery has prompted a blame game between Dorset Council, contractors at the barge and the Home Office about who was notified and when.

‘When was govt told about Legionella?’

The council went on to claim a Home Office staff member was informed about the bacteria on Tuesday.

However, a government source previously told Sky News there was no record of this conversation, and claimed the Home Office only received a written notification about the Legionella on Wednesday evening.

Downing Street repeatedly said the government had acted quickly after being informed about the traces of Legionella bacteria.

Asked if ministers would be looking into the role of the contractors, he said: “I think we will be communicating with all relevant groups to see if there are any lessons that can be learned, as you would expect in any public health situation.

“We remain confident that we have acted quickly once informed.”

Asylum seekers ‘not valued’ as humans

However, Number 10 said the Home Office was still “clarifying” when officials were made aware of issues on the Bibby Stockholm barge.

“Ministers were made aware on Thursday evening about the results of the test,” the spokesman said.

Pressed about who made the decision to put migrants on the boat before the test results for Legionella bacteria came back, he said it was a “decision taken by the Home Office in conjunction, having all the relevant tests being done and making sure that the checks are in place”.

“These are routine precautionary tests for Legionella which is why people were able to embark.,” the spokesman added.

This morning Health Secretary Steve Barclay said he still believed migrants should be moved back on to the barge in spite of the row, saying it was an important tool in reducing the £6m-a-day cost of housing asylum seekers in hotels.

Number 10 declined to say when people might return to the Bibby Stockholm barge, telling reporters it would not be “putting a timeline on that”.

“We do expect them to be back on the boat as soon as possible.

“The Home Office is awaiting the results of further tests.

Barge reminds migrant of Islamic State

“Once those have been completed, obviously the intention is to return people.”

The barge is one of a number of alternative sites the Home Office is using to end reliance on expensive hotels for asylum seekers, which the government says is costing the taxpayer £6m a day.

Its operation has been mired in controversy after it was delayed several times before it finally opened to asylum seekers last Monday.

Charities have warned that those on board the boat have been “re-traumatised” after they were evacuated following the discovery of Legionella.

Conservative ministers have faced calls to resign over the saga, with former cabinet minister David Davis saying the evacuation “revealed the startling incompetence of the Home Office itself”.

“It’s really, really hard to understand how, at all layers, this could not be caught early.”

The government believes the existence of the barge will serve as a deterrent to those arriving in England via small boats in the Channel.

However, in a further blow to the prime minister, last week saw the highest daily number of people cross the Channel, with 755 migrants making the journey on Thursday.

It brought the cumulative total since records began in 2018 to over 100,000.

The government was then forced to defend its immigration strategy after at least six people died after a small boat crossing from France to the UK capsized and sank, in what was described as an “appalling and preventable” tragedy.
