Spain responded to controls imposed by Italy with similar restrictions on Italian travelers, exacerbating a severe migration crisis and generating disputes among European partners.
Rome's initial decision to reintroduce controls on travelers from Spain was due to the mass arrival of immigrants in Ceuta.
Spain's response has magnified the mistake, opting for ultimatum and reciprocation instead of using community tools to demand Italy's restrictions withdrawal.
There are fears that this dispute will move to the heart of the European Commission, fracturing the balances between popular and socialist parties that sustain Ursula von der Leyen.
Conclusion: The escalation in tensions between Spain and Italy due to the migration crisis is deteriorating relationships amongst European Union partners and could threaten stability within the European Commission.
