This prompted a flurry of questions about whether the Government was planning to convert warehouses into dorms for migrants.

More than 32,000 people are currently staying in hotels, costing taxpayers £5.77m every day.

Military sites, former student accommodation, abandoned care homes, empty tower blocks and converted houses and flats could all be used to house asylum seekers.

And Ms Cooper revealed “industrial sites” are now under active consideration as well.

She told LBC: “Yes, we do also want to see alternative sites, more appropriate sites, including looking at military and industrial sites as well.

“But the core of it has to be clearing the numbers out of the system and preventing as many people getting into the system in the first place.”

Sunday Express columnist Nick Ferrari then asked the Home Secretary: “Is it a disused Carpet Warehouse or something? What is an industrial site?”

Ms Cooper continued: “Well, we’re looking with other government departments and looking with the local councils at what some more appropriate sites might be, and certainly more appropriate than asylum hotels. We have managed to cut the bill for these costly asylum hotels by nearly a billion pounds this year.”

But Mr Ferrari hit back: “But is it a warehouse? Is an industrial site a warehouse?”

The Home Secretary told LBC: “There are a range of different things that we’re looking at…”

Pressed again on whether industrial sites meant warehouses, Ms Cooper said: “That’s one of the things that’s been looked at. But we will provide updates when we’ve got the practical plans.

“What I’m not going to do, I’m doing the opposite, basically, of what the previous government did, because they used to just announce a whole load of things and then not actually deliver any of them.

“And I think that undermined trust.”

Ministers have set aside £500m to invest in a “new, more sustainable accommodation model” as they scramble to close 210 migrant hotels.

This “basic” accommodation, under the new cross-Government model, will be “used on a temporary basis” to house asylum seekers waiting for their cases to be processed.

The Home Office’s asylum accommodation providers are said to be looking for another 5,000 properties across the country to house 20,000 people.

Insiders suggested each flat would have two bedrooms on average, with space to house four migrants.

Labour has vowed to close every migrant hotel by 2029.

But Prime Minister Sir Keir Starmer on Monday revealed he wants to accelerate hotel closures.

And Ms Cooper on Tuesday insisted Labour could achieve this.

The Home Secretary told MPs the Home Office must slash the asylum appeals backlog to end the hotel crisis.

She said: “The biggest obstacle to reducing the size of the asylum system and to ending hotel use.

“Tens of thousands of people in asylum accommodation are currently waiting for appeals and under the current system that figure is to grow.

“With an average wait time of 54 weeks.

“We have already funded thousands of additional sitting days this year.”

Some 51,000 appeals are waiting to be heard.

A new independent body will be created to speed up asylum appeals, Ms Cooper said.

She added: “We will introduce a new independent body to deal with immigration and asylum appeals – fully independent of Government, staffed by professionally trained adjudicators with safeguards to ensure high standards, but able to surge capacity as needed, to accelerate and prioritise cases, alongside new procedures to tackle repeat applications and unnecessary delays.

“We’re also increasing detention and returns capacity, including a thousand-bed expansion at Campsfield and Haslar, with the first tranche of additional beds coming online within months to support many thousands more enforced removals each year.”

Fury erupted on Monday after it emerged judges blocked the closure of a controversial migrant hotel because housing asylum seekers in taxpayer-funded rooms is in “the public interest”.

Mr Justice Bean, Lady Justice Nicola Davies and Lord Justice Cobb said ensuring illegal migrants have accommodation is “the most important factor against” the injunction ordering the closure of the Bell Hotel in Epping, Essex.

And he said forcing them to move and change GPs would cause them disruption.

The three judges also sensationally claimed Epping Forest District Council could have applied for a court order to ban protests outside the Bell Hotel.

The shocking judgment revealed: “The most important factor against the grant of interim relief is the importance of the public interest in the accommodation of destitute asylum seekers.

“As noted above that is a public interest recognised by the imposition of a statutory duty on the Home Secretary and the use of the Bell to accommodate asylum seekers is an element in the performance of that duty.

“This is coupled with the consideration that those currently accommodated in the Bell will be required to move if interim relief is given and there will be a consequent disruption to their lives.

“All of them are now registered with local medical practices and there will be disruption in that respect as well as in the move to a different location.

“In that regard I reject the claimant’s contention that it will be less disruptive for those at the Bell to move now than it would be if they had to move later if an injunction is refused now but is ultimately granted.”

The judgment added: “Epping do not appear to have considered such alternatives either. These could either be measures taken by the police pursuant to s14 of the Public Order Act 1986, such as in fact occurred, or an application by the Council for an injunction against certain forms of protest.”

Shadow Justice Secretary Robert Jenrick said: “At the invitation of Yvette Cooper’s lawyers, the Court of Appeal ruled the public interest was in keeping illegal migrants in hotel accommodation, while the harms to Epping residents were put aside.

“It even encourages councils and the police to curb local protests rather than stopping the use of hotels housing illegal migrants.

“It’s there in black and white: the entire system has been turned against the British people.”
