Santiago Abascal, leader of Spain's far-right Vox party, has issued an ultimatum to the Popular Party (PP) regarding the distribution of migrant minors from the Canary Islands.
Vox threatens to withdraw from regional governments that agree to accept these migrants.
Abascal demands the PP use all political and legal means to prevent the distribution of unaccompanied minors across Spain.
This stance puts pressure on the PP, which governs several regions in coalition with Vox.
The ultimatum comes as the central government seeks to address the migrant crisis in the Canary Islands, where nearly 6,000 minors have arrived in recent months.
Vox links increased immigration to rising crime rates, a claim that has intensified the political debate on migration policy in Spain.
