British Interior Minister Suella Braverman will lay out plans on Tuesday for new laws that would forbid migrants from claiming asylum after crossing the English Channel, according to a government source.

According to Braverman’s staff, she would vow to looking into additional legislative powers so the government can deport anyone who enter Britain unlawfully during her speech at the annual conference of the ruling Conservative Party.

“It’s right that we extend the hand of friendship to those in genuine need,” Braverman will say, according to advance extracts.

“Parts of the system aren’t delivering. We need to end abuse of the rules and cut down on those numbers that aren’t meeting the needs of our economy.”

The new powers would go further than existing legislation and were designed to create a blanket ban on anyone who enters Britain illegally, including on small boats across the Channel, from claiming refuge, the source said.

The Home Office did not immediately respond to a request for comment.

The previous prime minister Boris Johnson had hoped that a plan to deport those arriving illegally to Rwanda, would act as a deterrent to those arriving in dinghies and small boats but numbers hit record levels over the summer.

The first planned deportation flight in June was blocked by a last-minute injunction from the European Court of Human Rights.

Braverman will say on Tuesday she intends to ensure Britain’s policy on illegal immigration cannot be “derailed by abuse of modern slavery laws, the Human Rights Act or the European Court of Human Rights”, her team said.
