Suella Braverman has unveiled a five-point plan for the Government to follow to stop the boats, demanding the Government cancel its Christmas break to tackle the “emergency”.

She warned Rishi Sunak against “tinkering with a failed plan”, saying this will not solve the crisis.

The former Home Secretary, sacked last week after writing an unauthorised Op-Ed criticising the police, also attacked “unaccountable” international courts.

Suggesting Sunak should change international law and quit the European Convention on Human Rights, Braverman warned: “There is no longer any chance of stopping the boats within the current legal framework.”

She added: “Having committed to emergency legislation, the Prime Minister must now give Parliamentarians a clear choice: to either properly control illegal migration or explain to the British people why they are powerless under international law and must simply accept ever greater numbers of illegal arrivals on these shores.”

Her five-point plan pitched as “five tests”, demanded the Government’s emergency legislation “address the Supreme Court’s concerns regarding Rwanda”, advising the Government to take “practical steps to improve Rwanda’s asylum system” rather than just declaring it safe in law.

She also demanded that the Bill enable flights to Rwanda before the election, which will take place in 2025.

Her third demand was that “swift removal must mean swift removal”, explaining: “Those arriving illegally must be removed in a matter of days rather than months as under the Illegal Migration Act.

“This means amending the Act to ensure that removals to Rwanda are mandated under the duty to remove, with strict time limits.”

Braverman’s fourth request is that those arriving in the UK illegally, such as via small boat, “must be detained”. She added: “Legal challenges to detention must be excluded to avoid burdening the courts, making it clear that detention is mandated until removal.”

Her fifth “test” is a call for the Government to treat the issue as an “emergency”.

She demanded: “The Bill should be introduced by Christmas recess, and Parliament should be recalled to sit and debate it over the holiday period.”

This came after the courts ruled that the plan to send migrants to Rwanda was illegal.
