Teresa Ribera has been nominated by European Commission President Ursula von der Leyen to become Europe’s new antitrust chief, succeeding Margrethe Vestager. Ribera, currently Spain’s Minister for Ecological Transition, will be responsible for enforcing the Digital Markets Act and overseeing compliance from major tech companies like Google and Apple. With a strong background in climate policy, Ribera is expected to adopt a rigorous stance on market dominance while balancing concerns over fostering European champions. She will also inherit ongoing investigations into the AI sector, as concerns rise about tech giants consolidating power. Ribera's confirmation by the European Parliament is pending, and her approach may significantly influence the future of regulatory practices in the EU. Her political career spans nearly two decades, highlighting her expertise and commitment to environmental and competition issues.
