The UK government's 'one in, one out' deal with France — announced with fanfare by Starmer and Macron in July 2024 — lasted 423 days before being quietly scrapped earlier this month. Of 40,000 small boat arrivals during its lifespan, just 1,500 were returned to France, a 4% rate. The thinktank that championed the policy calculated it would need a twenty-fold expansion to meaningfully deter crossings. Nearly 50 deported asylum seekers returned to the UK a second time. The government's replacement: doubling riot police along the French coast. The deal's failure is not an anomaly but a data point in a decades-long pattern. Each escalation in border security — from lorry-park fortification in Calais to coastal policing — eliminates one route and forces asylum seekers into more dangerous alternatives. When lorry access was locked down, dinghies appeared. When Calais policing intensified, 'mega-dinghies' launched from Normandy and Belgium, making longer, deadlier crossings. The spectacle grows worse with each iteration, feeding the political dynamics that demand further escalation. The humanitarian costs were severe. Nearly 100 children were misidentified as adults and wrongly detained under the scheme. Some asylum seekers deported to France were beaten by the smugglers they'd paid for the original crossing. Reporter Diane Taylor, who has covered asylum policy for 25 years, called it the most suffering she has seen caused to refugees by a UK government policy. French domestic politics appear to have killed the deal as much as operational failure. With immigration set to dominate France's next presidential election, Paris had no appetite to be seen absorbing Britain's unwanted arrivals. If Marine Le Pen wins in April 2026, cooperation could collapse entirely — France might refuse to take any asylum seekers from the UK, triggering a spike in crossings that would further empower the far right on both sides of the Channel. MI5's annual threat briefing, released the same week, warned that extremists with anti-immigration views are increasingly considering terrorist attacks against immigration centres and asylum hotels. The security apparatus is now tracking threats generated, in part, by the political spectacle that security-first border policy itself creates. Nigel Farage was forced to deny that a Reform UK government would authorise lethal force against small boats — a denial that reveals how far the Overton window has shifted. The fundamental structural problem remains untouched: there is no legal route for most asylum seekers to reach the UK. As long as wars, persecution, and instability generate displacement, people will attempt the crossing. Every security measure that blocks one path creates demand for smugglers to open another, more dangerous one. Daniel Trilling, author of 'If We Tolerate This,' frames it plainly: asylum is not an act of generosity but a necessary response to the world as it is. The government's pivot to more riot police is a continuation of the same logic that produced the problem. The policy treadmill turns: crackdown generates spectacle, spectacle generates political pressure, pressure generates crackdown. Twenty years of this cycle have made crossings more dangerous, more visible, and more politically toxic — the precise opposite of every stated goal.
