The British Prime Minister has promised emergency legislation and a new treaty with Rwanda to ensure his flagship asylum policy is not blocked again after the UK Supreme Court ruled that it was unlawful.
Rishi Sunak said he would end the "merry-go-round" of legal challenges with a law to deem the east African nation a safe country after his plans to "stop the boats" were blocked.
He is resisting pressure from the right of his Conservative Party to pull the UK out of the European Convention on Human Rights (ECHR) but vowed: "I will not allow a foreign court to block these flights".
The UK’s highest court rejected the government’s appeal over its policy of removing asylum seekers to Rwanda if they arrive by unauthorised means.
The five senior justices unanimously ruled that the plans are unlawful because there is a risk genuine asylum seekers could be forced back to their country of origin by Rwanda.
Sacked home secretary Suella Braverman demanded that Mr Sunak brings in laws to block off the ECHR, Human Rights Act and other routes of legal challenge.
He pinned his hopes firstly on brokering a new treaty with Rwanda that will provide a legal guarantee that asylum seekers will not be removed from the country.
Speaking in front of a "stop the boats" podium at a London new conference, Mr Sunak said he disagreed with the Supreme Court ruling that has jeopardised his promise to halt small boat crossings.
"But we need to end the merry-go-round.
"So I’m also announcing today that we will take the extraordinary step of introducing emergency legislation.
"This will enable parliament to confirm that with our new treaty, Rwanda is safe."
Mr Sunak said it will also "make clear that we will bring back anyone if ordered to do so by a court", meaning migrants sent to Rwanda could then be brought back to the UK.
But he repeatedly refused to say whether the first removal flight to the country would take off before the next UK general election, only saying he was aiming for "the spring".
Mr Sunak said he would be "prepared to do what is necessary" if the courts intervened "against the expressed wishes" of MPs.
He warned of challenges in the European Court of Human Rights, but said he was prepared to "revisit those international relationships to remove the obstacles in our way".
"So let me tell everybody now, I will not allow a foreign court to block these flights."

UK Home Office officials have been unable to say what will happen to the asylum seekers who remained in Rwanda after their claims were rejected, if they would not be removed.
Britain is expected to pay Rwanda more money for the new treaty, having already handed over £140 million (€160m) under the plans that have seen not one asylum seeker removed since it was announced in April 2020.
Mr Sunak was keeping the threat surrounding the ECHR on the table as Ms Braverman was waiting in the wings to challenge his authority after being sacked.
She said that he must change the law to prevent legal challenges, arguing there was "no chance of curbing illegal migration within the current legal framework".
"We must legislate or admit defeat," she wrote on social media, before an ally made clear she believes Mr Sunak's emergency plans are "more magic tricks" that will end up back in the courts.
His plan did echo the demand of former prime minister Boris Johnson, who argued that the "only one way to end the legal blockade on Rwanda" was for a law to designate Rwanda a "safe" country.
Labour Party leader Keir Starmer demanded an apology to the UK from Mr Sunak for wasting millions of pounds of taxpayers’ cash on the "ridiculous, pathetic spectacle".
Supreme Court President Robert Reed ruled there would be a risk of Rwanda returning genuine asylum seekers to face "ill treatment" in the country they had fled.

He made it clear in his summary of the judgment that he took into account the plan as well as domestic law.
Justice Reed agreed with a UK Court of Appeal decision earlier this year that there are "substantial" grounds to believe there is a "real risk" of refugees being returned by Rwanda to their home countries.
But he made it clear the judgment was based only on the current failure to "eliminate the risk" there and said the changes needed to reduce this "may be delivered in the future".
The UK Supreme Court’s ruling, though, made clear the challenges ministers must overcome, saying there was "evidence of a culture within Rwanda of, at best, inadequate understanding of Rwanda’s obligations under the Refugee Convention".

Campaigners welcomed the ruling, with the Freedom From Torture charity hailing it as a "victory for reason and compassion".
Chief Executive of the Care4Calais refugee charity Steve Smith described the Supreme Court ruling "a victory for humanity".
"Today’s judgment should bring this shameful mark on the UK’s history to a close."
The legal rulings were based on evidence that Rwanda has a "poor human rights record", citing British police warning Rwandans in the UK of credible plans by the nation’s government to kill them.
Concerns over political and media freedom were also raised, as was the inability of the Rwandan courts to act independently of the government.
Evidence from the UNHCR, the United Nations’ refugee agency, cited Rwanda’s 100% rate of rejection of claims from countries in conflict zones such as Syria, Yemen and Afghanistan.
This is despite the UK authorities often finding the claims are "well-founded".
The body also presented evidence of more than 100 cases of "refoulement" - the process of returning refugees to their origin countries - that have taken place after the UK agreed its deal with Rwanda.
More than 27,300 migrants have been detected making unauthorised crossings of the English Channel this year, according to official figures.
