Alexander Simpson, Asda’s general counsel, talks to Alex Newman about dealing with the horse meat scandal, the benefits of being part of the Walmart network and why he asks his team to get behind the tills at Christmas

Within half a mile of Alexander Simpson’s office beside the River Aire in Leeds are branches of Tesco, Marks & Spencer, The Co-op, Waitrose and Sainsbury’s. For Asda’s general counsel, as for all of his colleagues at the supermarket’s head office, the encirclement is a pressing reminder of the ferocious competition within the retail sector. Not that Simpson spends much time in the aisles of rival retailers.
