In this Omni Talk Retail interview, recorded live from World Retail Congress 2026 in Berlin, Chris Walton sits down with Judith McKenna, the former CEO of Walmart International and current Board Member at Delta Air Lines and Unilever, to discuss leadership, frontline retail culture, board governance, and how AI is beginning to reshape the retail industry.
