Small boats are no longer the UK's migration problem. The prime minister still treats them as if they are

SMALL boats are no longer the UK's migration problem. They never really were. Yet on Sunday, standing in Dover, Andy Burnham - the country's new prime minister, barely a fortnight into his tenure - pledged to be "relentless" in stopping them.

The performance was unmistakable. Mr Burnham pointed to the doubling of National Crime Agency officers tackling smuggling gangs, from 376 at the start of 2025 to nearly 800, with a matching increase on the French side. He cited 300 arrests of smugglers last year and the seizure of over 1,100 small boats and engines. The Home Office claims that the seized equipment, had it been used, could have facilitated 72,000 additional illegal crossings. The BBC could not independently verify the arithmetic, but the headline figures are plausible. The point is not whether the numbers are exact. The point is that the government has a story, and it needs to be told in the right town, with the right adjectives, before the right audience.

The data supports the performance, if only because the data already told a favourable tale. Small boat crossings in the first half of this year are down roughly 43% compared to the same period in 2025: fewer than 12,000 people arrived from France, versus nearly 20,000 the previous year. The full-year figure ending in March was around 39,000, only a 3% rise on the year before and well below the 2022 peak. Net migration to the UK fell to 171,000 last year, the lowest since 2012, according to the Office for National Statistics. Asylum applications are also down 9%. Mr Burnham inherits a problem that is already receding.

The trouble is that small boats have never been the problem. More than 700,000 foreigners arrived in the UK on work, study and family visas in the year ending March 2026, according to Home Office data shared by the migration research group InfoMigrants. Small boats account for roughly 5% of all entries. The real drivers of net migration are legal channels: student visas, skilled-worker permits and family reunification. These are not subjects that lend themselves to dramatic speeches in Dover. You cannot double the number of officers tackling a spreadsheet.

That is precisely why the small-boat theatre persists. The incentive structure is clear. Mr Burnham arrives at Number 10 after Keir Starmer's departure, inheriting a Labour government that has been under sustained pressure from Nigel Farage's Reform UK party on immigration. Reform's entire political identity is built on the image of uncontrolled Channel crossings. Mr Burnham needs to show he is not Mr Starmer - a prime minister who presided over record migration and collapsing poll numbers - and that he can credibly fight populism on its own ground. A pledge of relentless enforcement, delivered in the town where the boats land, is the cheapest way to do it.

To be sure, there is something to the enforcement story. The doubling of NCA and French officers represents a genuine investment in interdiction. Smuggling networks are criminal enterprises, and disrupting them has moral and practical merit. The average boat now carries roughly 65 people, up from 58 a year ago, suggesting that smugglers are adapting to tighter enforcement by packing more passengers onto each trip - a dangerous trend that enforcement alone cannot reverse. Yet enforcement has diminishing returns. Smugglers are adaptable. They shift departure points, use more powerful engines, and as the data shows, cram more people onto each vessel. The deeper question is what happens when the boats land. Over 90% of small-boat arrivals claim asylum. Nearly 40% of initial asylum decisions in the year to March 2026 resulted in grants of protection. When Home Office reconsiderations are included, the effective success rate of asylum appeals reaches 66%. That is not a sign of a broken asylum system; it is a sign that many of the people crossing from war-torn Eritrea, Afghanistan, Sudan, Iran and Somalia have legitimate claims. Sending them back is not legally straightforward, regardless of how relentless the government feels.

The political arithmetic is what makes the Dover speech so revealing. Mr Burnham has already dropped the digital-identity scheme that Mr Starmer's government pushed to verify migrant status - a cross-party committee of lawmakers had labelled it a fiasco. This is a useful first signal that the new prime minister is willing to abandon his predecessor's pet projects. But the small-boat pledge is not a new policy. It is a restatement of the old one, with fresher enthusiasm. The question is whether Mr Burnham's government will eventually turn its attention to the legal migration channels that actually determine the net migration figure.

It is tempting to think that the answer is no, simply because it is politically dangerous. Visa caps are a blunt instrument. They can distort labour markets, block sectors that genuinely need workers, and raise the cost of living further in an economy already straining. Mr Burnham's stated agenda - "rewiring" the economy to tackle the cost of living crisis - would benefit from a migration system that channels people into where they are needed, not one that indiscriminately restricts them.

The better answer is not more officers in the Channel. It is a migration system that distinguishes between the 700,000 people who come legally and the 40,000 who do not, and manages both with clear rules, realistic quotas tied to labour-market evidence, and asylum processing that is fast enough to prevent the current backlog of 48,758 pending initial decisions. The government has committed to ending the use of hotels for asylum seekers by 2029; that timeline is already too long. The 80,000-plus people waiting for their asylum appeals - nearly double a year ago - are a symptom of a system that processes claims at the speed of administrative fatigue.

Mr Burnham's "relentless" pledge is politically understandable. A new prime minister needs to establish control, and nothing establishes the illusion of control like a firm line drawn in the sea. The danger is that the performance becomes the policy. If the government continues to treat small boats as the migration problem, it will continue to look like a government that confuses optics with governance.

The real test is not whether the NCA can arrest more smugglers. It is whether Mr Burnham can reform the visa system that actually moves the numbers. That is the harder conversation. It will also be the one that matters.
