Border Force is bracing for more Channel migrant arrivals after dozens were spotted leaving a notorious beach in northern France.

Scores of asylum seekers were seen piling into a rubber dinghy in Gravelines, northern France, after high winds prevented smugglers from launching boats bound for Britain.

French patrol vessels are believed to be shadowing at least two migrant boats in French waters.

Border Force was overwhelmed on Wednesday as criminal gangs exploited the hottest day of the year so far to launch dinghies destined for the Kent coast, carrying hundreds of people.

The French rescue ship Abeille Normandie even escorted one migrant vessel four miles into British waters because Border Force Volunteer and Border Force Typhoon were already tied up with arrivals.

It waited until the British ships were able to come and pick up the migrants onboard.

Some 605 crossed in 10 boats last Wednesday, a record number for January, February or March.

Home Secretary Shabana Mahmood is to introduce new legislation on migration this week in a bid to take on Reform UK.

Ms Mahmood, during a visit to Denmark, revealed migrants’ right to permanent asylum will be scrapped.

Instead, they will be offered temporary status, which will be reviewed every 30 months.

If their country is deemed safe enough for them to return, they will be sent back. Only children who arrive in the UK unaccompanied will be exempt.

Until now, successful asylum seekers have been granted refugee status for five years and allowed to bring their families to the UK. They then got almost automatic fee-free permanent settlement with continued access to benefits and housing.

Refugees will also be required to “earn” their settlement rights by working and contributing to society.

They will have to wait up to 20 years before they can apply to settle in the UK – and up to 30 years if they arrived illegally via small boats across the Channel or by claiming asylum after overstaying work, student or visitor visas.

The right of refugees to bring over their families has been halted until a new system is introduced.

The policies have been modelled on those introduced by Denmark.

But she will not introduce plans to prevent “ghettos” forming in the UK.

According to a Government source, she is expected to say Britain will always provide sanctuary to people genuinely fleeing war and danger, but the generosity of the asylum system is attracting people from across the world, funding human traffickers and encouraging false asylum claims.

And the Labour Home Secretary refused to rule out paying migrants up to £30,000 to leave the UK voluntarily.

The She said more “generous” offers incentivise people to leave as she confirmed Labour will hike payments.

Foreign criminals, failed asylum seekers and immigration offenders currently receive up to £3,000.

Ms Mahmood refused to rule out a ten-fold increase, insisting only that “I haven’t made any final decisions on what the right sum is”.

She said: “I know it sort of sticks in your craw, basically, to think that you’re going to pay people who’ve come to your country illegally to leave and go back to their home country.

“What I would say to people, though, is when you look at the numbers, to house somebody in asylum accommodation, in a hotel, it costs £53,000 pounds a year per person every year, which is a huge sum of money that is going to waste at the moment.

“I think paying more than what we currently do is still going to be considerably less than what we’re spending on these people.

“I haven’t made any final decisions on what the right sum and the right sort of package will be for our country.

“It will be more than what we currently offer. And what I’ve seen here in Denmark is a more generous offer to get people to incentivise people to leave the country does work, because 95% of the returns that you see from Denmark are voluntary and people do make use of that incentivised package.

“It means that they do leave the country, and that’s very important.

“If we can get them out quickly and save a bunch of money in the process, I think it’s the right thing to do.”

Denmark is willing to pay up to 20,000 euros to convince migrants to leave the country voluntarily.

Migrants are also offered £2,258 if they withdraw their asylum claim within two weeks of arrival.
