UK’s upper house of parliament has demanded greater protections to be introduced before deportation flights can take off to far away Rwanda.
British Prime Minister Rishi Sunak has said he wants the first deportation flights to leave in the next few months – ahead of a general election expected in the second half of this year – so he can meet a pledge to “stop the boats”.
More than 2,500 asylum seekers have arrived in Britain on small boats so far this year.
In the most detailed financial assessment of the Rwanda policy, the British government’s spending watchdog on Friday said it would cost more 600 million pounds ($762 million) to deport the first 300 refugees.
Members of the UK parliamentās second chamber voted for five amendments to Sunakās controversial bill aimed at sending asylum seekers to Rwanda by the spring.
These five included an amendment introduced by Labour peer Lord Vernon Coaker, which inserted a clause into the legislation requiring āfull compliance with domestic and international lawā.
The government suffered a major setback with its plan to send asylum seekers to Rwanda last year when the Supreme Court ruled the policy was unlawful because it found there was a real risk asylum seekers could be sent back to their country of origin and their safety jeopardised.
Sunak sought to counter the ruling by upgrading an agreement about the plan between London and Kigali into a treaty, in which the Rwandan government committed to never sending any asylum seeker back to the country they originally came from.
He also promised legislation that declared Rwanda to be a safe country and disapplied parts of human rights law that could leave removal decisions open to legal challenge.
Peers on Monday backed a second amendment, brought by cross-bencher Lord David Hope, that stated Rwanda would be treated as safe only āwhen, and so long as, the arrangements provided for in the Rwanda treaty have been fully implemented and are being adhered to in practiceā.
The Lords also supported a third amendment that is meant to ensure there is a system in place to check that the UK and Rwanda have implemented safeguards set out in the treaty. The 110-vote majority in favour of the amendment marked Sunakās biggest defeat in the Lords since he became prime minister.

Peers are this week voting on almost 50 amendments to Sunakās bill, which is a key part of his efforts to fulfil his pre-election pledge to āstop the boatsā carrying migrants across the English Channel.
But last month the parliamentary joint committee on human rights joined the UN High Commissioner for Refugees, charities and immigration experts in warning that the bill was āfundamentally incompatible with the UKās human rights obligationsā.
Many of the amendments proposed by peers seek to strengthen human rights provisions in the bill.
Two further amendments approved by the Lords on Monday called for a means to challenge the presumption that Rwanda is safe should ācredible evidenceā emerge that suggests otherwise.
Coaker, a former Labour minister, said in the debate in the second chamber that the bill was evidence that the government āhas said the facts are not convenient so weāll change them by legislationā.
The Home Office said in a statement: āWeāre focused on delivering for the British people and stopping the boats. The prime minister has been clear that he will tackle this major global challenge with bold and innovative solutions, and the Rwanda scheme is just that.ā
Although the Rwanda bill is expected to face significant ongoing opposition in the Lords, it is likely to complete its parliamentary passage in the House of Commons in late March.
Downing Street said the government remained committed to sending flights toĀ RwandaĀ āin the springā.
Ministers hope sending some asylum seekers to Rwanda will deter others from making the perilous cross-Channel journey, and start to reduce the number of migrants coming to the UK via clandestine routes.
The Home Office said 327 people made the Channel crossing in small boats on Sunday, the second highest daily count this year.
Last week the National Audit Office, parliamentās spending watchdog, said the cost of Sunakās Rwanda policy could exceed Ā£580mn by the end of the decade. The vast bulk of the UK payments to Kigali would be in the form of aid payments.
The Commons public accounts committee responded to the NAO report by saying it would launch an inquiry into the costs of the UK-Rwanda partnership to scrutinise whether it represented āvalue for moneyā.
