A raft of earnings results kept the just-food news desk busy this week. M&S chief executive Marc Bolland insisted its product development sets it apart from rival grocers, while Campbell Soup CEO Denise Morrison expressed her disappointment at the firm's US soup performance this year. Elsewhere, just-food spoke with Peter Lauritzen, CEO of Arla UK, and Neil Kennedy, chief executive of Milk Link, on the merits of their merger.
