Humer said he was "delighted and honoured" to be offered the appointment. "Over the last two years I have come to know and admire Diageo's people and performance. I look forward to taking up broader responsibilities in the company."
Paul Walsh, Diageo's chief executive thanked Blyth for his commitment to Diageo over the last eight years. "During that time we have made considerable progress in building Diageo's position as the world's leading premium drinks business and I thank James for the significant contribution he has made to that.
"I look forward to working with Franz Humer. We have a shared view in Diageo's ability to develop as a truly sustainable global business through the delivery of continued commercial success; enhancing our financial strength and making further progress against our social and environmental policy commitments."
