So how WILL Trump deport 20 million? It's the bold pledge that helped propel him back into the White House. Now our US Editor reveals his $1trillion 'shock and awe' blueprint...

When Donald Trump is inaugurated arsenic America's 47th president connected January 20, the lawsuit volition people the authoritative commencement of his 2nd word successful bureau with cautiously stage-managed images that volition beryllium seen astir the world.

Within hours of the event, Trump volition instrumentality his spot down the Resolute table successful the Oval Office and motorboat what helium calls 'the biggest wide deportation successful American history'.

While the expulsion of amerciable immigrants was a focal constituent of Trump's predetermination campaign, the precise details of however helium intends to execute his extremity of removing arsenic galore arsenic 20 cardinal radical from US ungraded person mostly remained unknown.

Until now.

The Mail connected Sunday has spoken to those successful Trump's interior ellipse who accidental his migration plans person been apical of the database successful discussions held astatine Mar-a-Lago, his Florida home, successful the days since his crushing victory.

One lawyer acquainted with the talks told me: 'Donald is preparing for a bid of moves against amerciable immigrants, which helium says volition origin 'shock and awe'. Kicking retired illegals was the mainstay of his tally for the White House and helium knows radical expect enactment connected Day One. They volition get it.'

The root claims Trump volition instantly motion a bid of enforcement orders, the astir extremist of which volition beryllium to adjacent the border. 

Citing an migration crisis, helium volition temporarily unopen the confederate borderline to springiness officials a accidental to wide a immense backlog of cases. 

Trump claims that the Joe Biden medication allowed much than 10 cardinal radical to illegally participate the US, bringing the full fig of amerciable immigrants to 20 million.

There are plans to importantly summation the fig of equipped officers connected horseback patrolling the rugged terrain adjacent to the US's borderline with Mexico. 

And, of course, operation volition resume connected the infamous partition moving betwixt the 2 countries, which was a cardinal – if unfulfilled – plank of Trump's migration argumentation during his archetypal term. 

Having lengthened the partition to astir 700 miles (of the adjacent 2,000-mile border), enactment abruptly stopped erstwhile Biden came to power. Trump has vowed to implicit the $8 cardinal occupation by inviting businesses to 'sponsor' sections.

'Step One' of the deportation programme is to people undocumented immigrants with ties to transgression gangs. 

It is dubbed 'Operation Aurora', aft the Colorado municipality wherever members of the ruthless Venezuelan thoroughfare pack Tren de Aragua turned flat complexes into bases for cause dealing and prostitution.

Trump plans to invoke the Alien Enemies Act of 1798, which gives presidents the authorization to detain and deport non-citizens from 'hostile nations' during times of warfare and conflict. The instrumentality was utilized to warrant the gathering of Japanese internment camps during the Second World War.

According to those acquainted with Trump's plans, helium volition people the 700,000 Venezuelans, Haitians, Cubans and Nicaraguans helium has branded 'vicious criminals from countries that hatred us', who person been allowed to enactment successful the US nether a Biden parole programme.

And what if, arsenic is highly likely, countries garbage to instrumentality backmost convulsive pack members? Trump volition chopped disconnected assistance and prohibition travellers from those countries from entering the US, adjacent connected tourer visas.

'Step Two' is to expel much than 1 cardinal radical whose applications to stay successful the US person been denied and who are connected the deportation list.

Then the round-up of the millions of remaining amerciable immigrants volition statesman arsenic portion of 'Step Three'. Places of work, including farms and meatpacking plants, volition beryllium taxable to raids (or 'targeted enforcement activities') – thing the American Civil Liberties Union calls 'vile, unconstitutional and un-American'.

Individuals volition beryllium taken to 'holding centres' earlier their deportation is fast-tracked.

Experts accidental the outgo of the archetypal 2 steps could beryllium arsenic overmuch arsenic $300 cardinal and the outgo of expelling each amerciable alien – thing adjacent Trump privately admits is intolerable – could beryllium arsenic overmuch arsenic $1 trillion.

The MoS understands Trump is considering deploying the subject and National Guard to physique 'tent cities' connected unused national land, including spot belonging to schools and prisons.

He volition reintroduce the 'Remain successful Mexico' Act, which volition compel imaginable immigrants – mostly from Central and South America but progressively from China and Eastern Europe – to enactment connected the confederate broadside of the borderline portion their visa applications are processed.

Ronald Vitiello was manager of Immigration and Customs Enforcement (ICE) during Trump's archetypal word successful office. His predecessor was Tom Homan, the antheral present anointed by Trump arsenic his 'Border Czar'.

Mr Vitiello told the MoS: 'We wouldn't beryllium contemplating removing 20 cardinal radical if they [the Democrats] didn't fto them each in. It's a travesty we're successful this concern and it's wholly preventable.

'Enforcement is difficult, costly and risky for frontline operatives, but precise necessary.

'The ICE is going to person to find radical who don't privation to beryllium found, program harmless apprehension and custody, find a spot for them to stay, person owed process successful court, and the logistics to nonstop them home.' So however precisely volition it work?

Trump is said to beryllium planning to merge ICE and Border Patrol – the national instrumentality enforcement bureau – into 1 'uber' organisation of 88,000 people and volition merchandise millions successful cardinal backing to adhd 40,000 caller agents and 8,000 other migration tribunal judges to expedite expulsions.

Ira Mehlman, from the Federation for American Immigration Reform (FAIR), is reportedly advising the incoming Trump administration. 

He said past night: 'There are astir 647,000 radical with transgression records who person been allowed into the United States. Of those, 435,000 person convictions, including 13,000 murderers. Nobody's going to miss them if they're sent home.'

But however volition authorities find those who don't privation to beryllium found?

'It's similar uncovering immoderate criminal,' a instrumentality enforcement root told me. 'You people their homes, the radical who are financially supporting them. These radical are not rocket scientists. If you enactment unit connected their families to springiness them up, 9 times retired of 10 it works.'

Mehlman defended raids connected businesses saying: 'The Government volition spell aft employers who prosecute amerciable immigrants. They person concern licences and assets. You spell successful there, you bust the employers for violating the laws and you nonstop a precise wide message.

'Their rival down the street, who mightiness beryllium doing the aforesaid thing, mightiness past think, 'I don't privation to hazard this,' and volition halt hiring amerciable immigrants.'

But it is the rounding up of the bulk of migrants nether 'Step Three' that volition apt nutrient the defining images of Trump's 2nd term.

Many of these radical volition person children, aft being successful the US for years. Pictures of families being torn apart, of children being ripped from their parents' arms, could backfire connected Trump.

But the lawyer who has been speaking to Trump's squad says: 'What you person to retrieve is that President Obama deported 5 cardinal people, and nary 1 talks astir that due to the fact that he's a Democrat.'

It was nether Obama, helium observes, that arguable chain-link obstruction enclosures – oregon cages – successful deportation holding centres were archetypal built. 'President Trump has a nonrecreational squad astir him,' says the lawyer. 'The champion of the best. They person been moving connected this migration program for years.'

And, crucially, Trump 'has the mandate of the people'.

He insists that the President-elect isn't against immigration, pointing retired that Trump is joined to Melania, a Slovenian-American; his archetypal woman Ivana was calved successful what was past Czechoslovakia; and Elon Musk, 'his champion buddy', hails from South Africa. 

'He wants to marque the American Dream achievable again, but lone for radical who person the ineligible close to beryllium here,' helium says.

Intriguingly, Trump is exploring paying 'third-party harmless countries' to instrumentality non-violent applicants portion their visas are being processed. The strategy is akin to Rishi Sunak's present abandoned Rwanda plan, successful which migrants who crossed the Channel illegally were to beryllium flown to Rwanda to question asylum determination instead.

The root said: 'Trump isn't a monster. He understands galore asylum seekers whitethorn look decease if they person to instrumentality to their state of origin. There volition beryllium harmless third-party countries which volition location these radical astatine immoderate outgo to the US taxpayers. But they volition beryllium the exception, not the rule.'

Alfonso Aguilar, erstwhile main of the US Office of Citizenship nether President George W. Bush, told the MoS: 'The biggest situation volition beryllium communicating the migration argumentation to the American radical earlier the Democrats outcry that it's a humanitarian situation oregon cruel and inhumane. The Trump medication volition request to amusement that this is simply a just and conscionable process.'

The American Civil Liberties Union has amassed a squad of lawyers to combat deportations, portion California politician Gavin Newsom says nationalist defenders volition beryllium disposable to each amerciable immigrants 'to guarantee they get a just trial'.

But Trump volition effort to bypass existing quality rights laws and present 'deport now, inquire questions later' legislation, and helium has the numbers to bash truthful fixed his party's power of the Senate and House of Representatives.

Furthermore, ineligible challenges volition yet extremity up successful the Supreme Court, which is presently weighted successful Trump's favour.

No uncertainty the deportation program volition contiguous a bumper payday for lawyers, but operation and transport companies volition benefit, too. While the volition is to usage national housing, the subject and borderline agents, the sheer size of the occupation means it is apt the Government volition prosecute contractors to physique impermanent lodging and supply other planes for transportation. 

Tellingly, wrong 24 hours of Trump's decisive triumph connected November 6, shares successful 'private prison' firms specified arsenic CoreCivic and Geo Group surged.

Many fearfulness Trump's plans could severely harm the US economy, often citing the illustration of Florida wherever politician Ron DeSantis issued the country's astir stringent anti-illegal migration orders 18 months ago.

Today, farmers successful the authorities kick they bash not person capable radical to prime Florida's trademark oranges, portion tiny concern owners accidental they are being forced to unopen down due to the fact that Americans don't privation to bash menial jobs.

One edifice proprietor who gave his sanction lone arsenic 'Charles' said: 'It's pugnacious to find radical to lavation dishes. American students don't privation to bash this.

'If Trump gets escaped of everyone doing the dirtiest jobs, past who volition bash them?'

'There whitethorn beryllium shortages astatine first, immoderate holes successful the system,' concedes the lawyer adjacent to Trump. 'But astir amerciable immigrants travel present due to the fact that they privation to work, they privation to make a amended beingness for their families. All we are saying is, bash it properly.'

Whether businesses that trust connected imported labour volition spot it successful specified elemental presumption remains to beryllium seen, arsenic does the spot of protestation from the bluish fractional of America that voted Democrat. 

What is much definite is that the occurrence oregon different of Trump's program to deport immoderate 20 cardinal radical volition find the destiny of his 2nd term.
