GB News' Home and Security Editor Mark White has revealed what happens to migrants when they are caught illegally working in the UK - and he admitted the answer will "infuriate" viewers.Earlier today Yvette Copper announced a new package of measures to crack down on illegal migration as part of Labour's manifesto pledge to "smash the gangs."

The package had a particular emphasis on those working in the UK illegally and set out that those employing illegal migrants would face harsh penalties.

However, when GB News host Bev Turner asked Mark what the punishment would be for the illegal migrants themselves if they were caught disregarding the law for a job, he explained that they would be "released on bail."

He said: "This will infuriate our audience, but many of them are processed and then released on bail and many of them just disappear back into the illegal economy.

"That is the sort of cat and mouse game that immigration enforcement is involved in. Now, part of what the government is planning to do, which is effectively adopting the policy of the previous government, is to open some of these old immigration detention removal centres.

"So that will mean some of those they believe are at higher risk of absconding they can put into immigration removal centres.

"But you can only do that for a certain amount of time.

"You can't leave them in there indefinitely. It has to be at the end process where you know that their legal challenges have been pretty much exhausted."

Detailing what the centres are, he explained: "They've always existed under multiple governments and they are the places when you're deemed to be illegal, either a visa overstayer, a foreign national offender that's just been released and they want to return you to your home country or a failed asylum seeker, for instance.

"If they believe you might not turn up for your plane to be deported, you're held in these centres.

"And they have always been, former prisons, former psychiatric hospitals, things like that, that have been converted into these immigration enforcement centres.

"So Labour might not like the issue of locking up people, but they realise within a government where you have to have control of your borders you need an ability to forcibly remove those who have no right to be here, then detention is an element of the enforcement strategy that you would have."

Outlining her plan today Yvette Cooper said that there will be a "major increase in returns" when it comes to illegal immigration.

She also said that she aims to achieve the highest rate of removals over the next six months for five years.

According to Labour, the number of migrants crossing the Channel since the election is 14 per cent lower than the same period last year.
