A TINY ENCLAVE on Morocco's coast has done what decades of Brussels diplomacy could not. The arrival of some 49,000 migrants in Ceuta in a single day last week has exposed the deepest fault line in the European Union: the arrangement by which most countries enjoy open internal travel while a handful guard the external border.
Spain's prime minister, Pedro Sánchez, has denounced the reaction of fellow EU leaders who are calling for Spain's suspension from the Schengen area - the EU's border-free zone. Italy's prime minister, Giorgia Meloni, was the most strident. Denmark and Finland followed. France and Germany were less bellicose but still demanded stronger borders. Mr Sánchez's complaint is understandable. It does not, however, address the incentives that produced the crisis.
Ceuta is a six-mile-long peninsula with a population of around 85,000. Together with Melilla, it represents the EU's only land frontier with Africa. It is Spain's geographic misfortune, not a policy choice, that has made the town a pressure valve for every economic, political and humanitarian failure in sub-Saharan Africa and the Middle East. Nearly 50,000 people arriving in a single day dwarfs even the 2021 surge, when some 10,000 made the crossing over several days. It is the largest surge of irregular arrivals ever recorded on a single day in EU territory.
Quick Backtesting Tool
The trigger is instructive. Earlier this month Spain's Supreme Court ruled that the special "summary return" rules - which allow for immediate expulsion of people intercepted at borders - cannot be applied to migrants intercepted at sea near Ceuta or Melilla. The Interior Ministry says smuggling networks exploited the ruling, encouraging mass sea crossings in the knowledge that immediate rejection would be harder. At least 19 people drowned. Reception centres in Ceuta, home to a population smaller than many London boroughs, were overwhelmed. The local government asked Madrid to declare a national emergency and deploy the army. The national government refused, arguing that migration does not fall within the legal framework governing such declarations.
Spain is caught between its own policies and geography. Mr Sánchez's government launched the seventh mass regularisation of undocumented migrants in Spanish democratic history earlier this year, a programme intended to grant legal status to an estimated 500,000 people. Nearly 1.2 million have applied, according to the Atlas Institute. The rationale is partly moral - more than two million Spaniards emigrated between 1960 and 1973 - and partly demographic. Spain's ageing population and sub-replacement fertility rate mean it needs foreign workers to sustain growth, fill vacancies and keep the pension and health systems solvent. As Real Instituto Elcano, a think-tank, has noted, the foreign-born population surpassed 10 million in 2025, just over 20% of the total.
A welcoming policy for those already inside Spain does not immunise it from a border surge. On the contrary, the regularisation programme may have strengthened the signal that Spain is a desirable destination, even as the Supreme Court ruling weakened the tools to manage arrivals. That is a self-inflicted complication. It is not the same as the broader structural problem.
Which is why the Schengen-suspension bluster from Italy and its allies looks hollow. Under the Schengen rules, a member state may reimpose temporary internal border controls if the system faces a serious threat. But Ceuta does not benefit from free movement to the rest of the Schengen area - a detail that even President Emmanuel Macron, usually reluctant to embarrass Mr Sánchez, pointed out. The European Commission has confirmed that no onward movement of migrants from Ceuta to mainland Spain has been detected. Spain is containing the crisis on its own terms, and so far it seems to be working: more than 48,000 migrants have been returned to Morocco, according to the latest figures.
The threat to suspend Spain from Schengen is therefore more political than practical. It is an attempt by right-wing governments, which have built electoral success on anti-immigration rhetoric, to turn Spain's geographic vulnerability into a weapon against a Socialist government whose pro-migration stance they despise. Italy's foreign minister, Antonio Tajani, explicitly linked the crisis to Spain's regularisation programme. The implication is that Spain's generosity at home created the flood at its border. That conflates two separate phenomena. Smuggling networks, a court ruling, and Morocco's uncertain role are the proximate causes. Spain's amnesty is background noise.
Morocco's involvement remains unclear. The kingdom guards its own border with Ceuta and periodically allows crossings for diplomatic leverage. In 2021, a similar surge followed a deterioration in bilateral relations. Whether King Mohammed VI authorised or simply tolerated last week's movement is unknown. What is known is that the Moroccan Interior Ministry did not respond to requests for comment. The ambiguity is itself a feature of the system: Morocco controls the tap.
The deeper problem is that Schengen was designed without a theory of burden-sharing. The agreement presumes that every member state will defend its external borders with equal capacity and incentive. In practice, southern and eastern members bear a disproportionate share of the pressure while northern and western members reap the travel benefits. The EU has patched this gap with ad hoc funding, Frontex deployments and reluctant solidarity. None of these mechanisms activate automatically. They require political will, which is scarce when the crisis hits someone else.
To be sure, the EU's response to the 2015 crisis was chaotic and costly. The Dublin system, which assigns responsibility for asylum claims to the first country of entry, was overwhelmed and never properly reformed. But the lesson of 2015 was not that open borders are impossible; it was that uncoordinated ones are. The current architecture forces frontline states to choose between humanitarian disaster and unilateral closure.
The Schengen-suspension demand from Italy and its allies is unworthy of serious consideration. Ceuta's special status means the threat is legally incoherent as well as politically opportunistic. What Spain needs is not exclusion from the system it is trying to defend but a framework that distributes the cost of defence more fairly. That means mandatory relocation quotas, a permanent relocation mechanism that activates when a single member's arrivals exceed a threshold, and genuine financial solidarity rather than the episodic pot-luck of current arrangements.
Mr Sánchez's own policy choices deserve scrutiny. The timing of the regularisation programme, the Supreme Court's narrowing of expulsion powers, and the reluctance to declare an emergency have compounded an already unenviable position. But a government should be judged on whether it understands the incentives it is creating, not merely on whether its neighbours agree with its values.
The Ceuta surge will subside. It has already begun to: the border has been reinforced, Morocco and Spain are coordinating, and the initial flood has been stemmed. The test is what happens next. If the EU responds with more posturing and less architecture, the next surge will be worse. And the next one after that.
The aim should not be fewer migrants at Spain's border by making Spain a less desirable destination. The aim should be a system in which the cost of being on the frontier is shared, not punished. Mr Sánchez is right that Europe's reaction has been selfish. He would be wiser still if he fixed the incentives that make his geography a political liability.
