Glasgow, United Kingdom - British Prime Minister Rishi Sunak is currently grappling with a potential rebellion from members of his own party as he pushes forward with his latest plan to send asylum seekers to Rwanda. Sunak's proposal aims to discourage migrants from crossing the English Channel to Britain in small boats by resettling them in the African nation.

However, the UK Supreme Court's recent decision to strike down the original legislation on the grounds that Rwanda is not a safe country for asylum seekers has forced Sunak to introduce the Safety of Rwanda Bill. This new bill aims to make it harder for courts to challenge British deportations to Rwanda, despite concerns that the policy may contradict international law.

As Tuesday's crucial House of Commons vote on the policy approaches, Sunak faces criticism from both within his party and from further right-leaning Conservative politicians who believe the plan is not "sufficiently watertight." Amidst worries of potential legal and international law complications, concerns about Sunak's leadership have arisen, reminiscent of former Prime Minister Theresa May's struggles to navigate Britain's exit from the European Union.

Last week, British immigration minister Robert Jenrick resigned, accusing Sunak of overseeing legislation that was unfit for purpose. However, the embattled Prime Minister denies that Tuesday's vote is essentially a vote of confidence in his premiership.

Opinion polls paint a grim picture for Sunak, showing that he is facing political annihilation in the next general election, scheduled for no later than January 28, 2025. Despite being the first Briton of Asian descent to hold the UK premiership, Sunak's efforts to revive the Conservative Party's prospects have so far fallen short, with the party remaining behind the opposition Labour Party by approximately 20 points in opinion polls.

Sunak has made his anti-immigration "stop the boats" campaign a focal point of his government's agenda in an attempt to win back right-wing voters who have shifted their support to the Labour Party. However, experts suggest that these voters alone will not secure Sunak's re-election.

Critics argue that the proposal to deport asylum seekers to Rwanda, a deprived country located 6,400km (4,000 miles) away from the United Kingdom, is both cruel and impractical. Some believe that the policy was formulated to appease the Conservative right, igniting debates about Britain's approach to refugee and asylum claims.

Central Africa expert Phil Clark argues that the UK's refusal to deal with refugee and asylum claims on its own shores should make the country a "human rights pariah." Clark also highlights the growing trend among Western states to outsource their refugee responsibilities to poorer nations, with Denmark and Austria reportedly pursuing similar migration deals with Rwanda.

If Sunak manages to maintain his authority following Tuesday's vote, he is expected to continue pushing for the legislation that would justify the £240 million ($300 million) already allocated to Rwanda as part of the deal. However, analysts remain skeptical about the long-term benefits of pursuing such a contentious piece of legislation so close to the next general election.

Most voters, it appears, are primarily concerned with the cost of living and the state of the National Health Service, viewing the asylum plan as a divisive distraction amidst internal party conflicts. Divided parties historically struggle to win elections, which adds to the challenges faced by Sunak and his MPs.
