Dozens of small boat migrants deported under 'one-in, one-out' deal return to Britain

Another unknown figure managed to return to Britain undetected

Dozens of small boat migrants who were deported under the "one-in, one-out" deal have returned to the UK.

Nearly 50 asylum seekers that were returned to France made their way back to Britain after the scheme was brought into force from September.

Home Office figures show 1,087 (four per cent) of migrants were returned across the English Channel, from data from August 4 last year until June 30 earlier this year.

During that same time period, 27,920 asylum seekers made the illegal crossing on small boats.

But an unknown number have returned while staying undetected by authorities, The Guardian revealed.

Upon entering No10, Andy Burnham vowed to be “relentless” in handling the small boats crisis despite a staggering 2,000 migrants entered Britain during his first fortnight in power.

The Prime Minister insisted “progress is being made” but admitted there was “more to be done” while visiting Dover.

During his tenure so far, people smugglers have started to switch up tactics in a bid to dodge French and English authorities.

“The number of crossings is down by 50 per cent this year compared with the same period in 2025 and the month we've just had,” the Prime Minister said.

“July has been the lowest number for six years of people crossing, so clearly progress is being made. But we're not complacent.

“It's why I am here. It's why I've come down on Sunday to see the team, to listen to what they think needs to be done, what further can be done."

BRITAIN'S BORDERS CRISIS - READ THE LATEST:

Labour was already forced to re-write the "one in, one out" deal with France after they discovered the very loophole that let deported migrants re-enter Britain illegally.

British ministers and their French counterparts have agreed to amend the flagship treaty signed last year amid concerns migrants have returned to the UK in lorries.

Home Office insiders confirmed the treaty has been extended until October before a decision is made on whether it will be made permanent.

While the scheme was set to expire at the end of June, a three-month extension had been agreed to cover the summer months in the Channel, when more crossings tend to take place due to the improved weather conditions.

Concerns over the small boats crisis skyrocketed across Europe since 72,000 migrants stormed Ceuta, the Spanish exclave on the African mainland.

At least 2,500 migrants remain at large in the city after the Spanish army were deployed to restore order and return them to Morocco.

Director of the Border Security and Immigration Centre at the Heritage Foundation, Lora Ries, told GB News the threat “absolutely needs to be a concern” for the UK.

At least 88 people are known to have died in the carnage, sparking outrage in Europe with fears the invaders could make their way into the UK - as well as the rest of Europe.
