PRIME Minister Pedro Sanchez hit back at Elon Musk after the tech billionaire appeared to criticise Spain’s plan to legalise 500,000 undocumented migrants. On Wednesday, Musk retweeted a post on X that claimed Sanchez’s move was aimed at expanding his voter base, adding only the caption: “Wow.”A few hours later, Sanchez responded to Musk’s post with: “Mars can wait. The exchange comes after Spain announced its decision to grant legal status to roughly 500,000 undocumented migrants earlier this week. The move aims to integrate workers into the formal economy and addressing labour shortages in sectors such as agriculture, healthcare, and hospitality, the government said. Sanchez’s government argues the regularisation plan is primarily economic, designed to bring hundreds of thousands of people who are already living and working in Spain into the legal system.
