The UK Immigration Debate Explained: What Each Party Would Do About Channel Crossings

Immigration dominates Westminster like almost nothing else. Small-boat crossings have fallen sharply this year, yet ministers were forced on to the back foot when 781 people arrived in a single day in September. A sweeping new Immigration and Asylum Bill is working its way through Parliament. And every major party claims it alone has the answer. Here is where each side actually stands.

The numbers: where things stand

On 23 September, the Home Office recorded 781 arrivals in ten boats, the highest single-day total of 2026. Two days earlier, boats had twice landed without being intercepted, at Samphire Hoe near Dover and at Folkestone. Home Secretary Shabana Mahmood called that "not acceptable" and ordered an urgent review by the Border Security Command. Education Secretary Lucy Powell took a different tone, saying "you can't stop everything all of the time".

The wider picture is more encouraging for the government. Provisional Home Office figures put arrivals at 18,565 for the year to late September, down 42% on the same point in 2025 and 26% below the same point in 2024. Le Monde's analysis of official figures found arrivals over the first eight months of the year down 44% on 2025, with around 17,000 crossings. Boats between June and August were the fewest since 2019.

Some context matters here. About 95% of people who reach Britain by small boat go on to apply for asylum, and roughly 59% are granted it, according to official figures cited by Le Monde. Whatever the rhetoric, most arrivals are entering the asylum system, not evading it.

How Britain got here

Small-boat crossings were rare before 2018 and then grew fast, topping 45,000 in 2022. The Conservative government answered with the Rwanda plan, announced in 2022: people arriving without permission would be sent to Rwanda to claim asylum there. The Supreme Court ruled the scheme unlawful in November 2023. The government passed emergency legislation declaring Rwanda safe, but no flight ever took off. Labour's Keir Starmer scrapped the plan in July 2024, calling it "dead and buried", at a reported cost of £700 million. Rwanda later sued Britain for £50 million at the Permanent Court of Arbitration; the court ruled for the UK in June 2026.

In place of Rwanda, Labour created the Border Security Command to pursue, disrupt and arrest people-smuggling gangs. Starmer's government struck a one-in-one-out returns pilot with France, signed in July 2025 and operating from August, under which Britain could send back small numbers of arrivals in exchange for taking asylum seekers from France. Paris began exit talks in September 2026, a story this site reported this week. Andy Burnham, who became prime minister in July 2026, has kept the broad enforcement approach while pushing new legislation.

The government's plan: Labour

Labour's centrepiece is the Immigration and Asylum Bill, introduced to the Commons on 30 June 2026 and passed at second reading on 13 July by 264 votes to 90. It is now in committee, with the Public Bill Committee expected to report by 3 November.

The Bill would create an Independent Immigration Appeals Authority to replace the First-tier Tribunal as the forum for asylum appeals, with hearings expected from late 2027. It tightens the application of Article 8 of the European Convention on Human Rights, the family-life provision the government says is routinely stretched to block removals. It replaces asylum, refugee and humanitarian protection claims with a single "core protection" model, reforms the modern slavery framework, and lets the Home Office require people on asylum support to make contribution payments once they can afford to.

Labour MPs back the Bill as a way to make the system fast and fair: claims heard quickly, foreign criminals removed more easily, genuine victims of trafficking protected. The Home Secretary has told MPs the aim is parity between refugees and other migrants on family reunion rules. Critics, including UNHCR, warn the changes risk breaching international protection standards and penalising trafficking survivors.

The Conservative plan: "Stronger Borders"

Kemi Badenoch unveiled the Tory "Stronger Borders" plan at the party's October 2025 conference. Its headline is a beefed-up Removals Force, with its budget doubled by an extra £820 million a year, funded in part by closing asylum hotels. The party set a "mandate" to remove at least 150,000 people a year, 750,000 over a Parliament, roughly five times the 35,000 removed last year, most of them voluntarily.

The detail is blunt. People who enter illegally would be banned from ever claiming asylum. The immigration tribunal would be abolished, with the Home Office deciding cases and only limited appeal rights. Immigration cases would get no legal aid, which the party says is abused by "coaching" solicitors. Asylum would go only to people threatened by a foreign government, not those fleeing conflict or intolerant laws, so "few people will qualify". Countries that refuse to take back their nationals would face visa sanctions. And the Conservatives would leave the European Convention on Human Rights if elected, saying it frustrates removals.

Badenoch has called the government's France deal "one thousand in, one out". Asked on the BBC where deportees would go, she said they should "go back to where they came from".

Reform UK's plan: "Operation Fortress"

Nigel Farage's party offers the most dramatic plan. Under "Operation Fortress", unveiled in August 2026, Reform would deploy the Royal Navy to intercept every small boat in the Channel and return the occupants under escort to France or Belgium. Farage calls it "the largest military operation in the English Channel since World War Two" and claims "within a fortnight, there would be no more boats".

The plan sets out a joint military command drawing on the Royal Navy, Royal Marines, RAF and British Army, plus a surveillance command to track incoming vessels. River-class offshore patrol vessels would do the intercepting. People would be detained, given food, water and a medical assessment, then transported back across the Channel, with a Bay-class landing ship providing detention capacity at sea for up to 700 people. Home affairs spokesman Zia Yusuf says former senior military figures back the scheme and the party would pass emergency legislation if needed.

The hurdles are obvious. France says the plan "would be a violation of French sovereignty as well as a violation of maritime law and international law". Retired Royal Navy commander Tom Sharpe told the BBC that Border Force, not warships built for anti-submarine work, is the right tool, and that the Navy has "basically none" of the ships the operation would need.

Reform pairs this with "Operation Restoring Justice": a pledge to deport 6,000 people a week, five deportation flights a day, detention capacity for 24,000 people including converted former military sites, and an estimated £10 billion cost over five years. Like the Tories, Reform would take Britain out of the ECHR.

The Lib Dems and the Greens

Sir Ed Davey wants Britain to negotiate joining the EU's Migration and Asylum Pact, unveiled as Lib Dem policy in August 2026. That would let Britain return some arrivals to the EU country they travelled from and give access to EU biometric databases, restoring something close to the pre-Brexit returns arrangement. Davey blames Brexit for the crossings problem and accuses Reform and the Tories of exploiting it. He notes arrivals are down 44% and deportations up 8% under Labour, but says that is "not anywhere near enough".

The Greens take the opposite approach from enforcement-heavy plans. Deputy leader Rachel Millward has called Reform's deportation proposals "ill-thought-out and cruel" and says the answer is safe and managed routes for asylum seekers, tackling root causes such as war, poverty and the climate crisis, and international cooperation rather than deterrence.

What happens next

Three things will decide where this debate goes. First, the Immigration and Asylum Bill's committee stage: its report is due by 3 November, and any government climbdowns there will set the tone. Second, France's exit from the one-in-one-out deal, which removes the government's flagship returns route and forces a rethink. Third, the polls. A recent YouGov MRP poll projected a hung parliament at the next election, due in 2029, with Labour on 241 seats, the Conservatives on 130 and Reform on 123. With Reform level with the Tories, immigration policy is no longer a side argument. It is the ground the next election will be fought on.
