Diageo GB has today announced that Barry O’Sullivan will become Managing Director of Diageo Great Britain, effective July 1.
Nuno Teles, the current Managing Director of Diageo GB, will move to Managing Director of Diageo Mexico. Nuno will continue in his existing role until Barry’s arrival.
Barry has spent the past four years as Managing Director of Diageo Ireland, delivering consistent, sustainable growth in the Island of Ireland market. Updates under Barry’s leadership includes last year’s ground-breaking investments in Guinness, with €100 million dedicated to decarbonising Dublin’s St. James’s Gate and a €30 million investment in the production of Guinness 0.0.
Barry joined Diageo Ireland in 2021 after serving as managing director for Mars Petcare in Australia and New Zealand, with previously roles for Mars in Mexico, the Middle East, Turkey and Africa.
Nuno joins Diageo Mexico after three very successful years in GB, where he consistently grew the business despite challenging market conditions. Nuno has also made bold decisions to reshape the GB business, including last year’s creation of the Diageo Luxury Company to streamline and refocus the market’s focus on the luxury sector. Nuno has always championed a people-first culture at Diageo GB, ensuring Diageo’s purpose of celebrating life every day thrives in GB culture.
“I cannot wait to get started in Diageo’s home market of Great Britain, where some of the country’s most iconic and loved brands are at the heart of celebrations." said O’Sullivan. "After four wonderful years in Ireland, I look forward to bringing my experience to this new role and build on the incredible legacy that Nuno leaves behind.”
Nuno Teles said: “While I am excited by the opportunity ahead, I will be very sad to leave the remarkable market that is Diageo GB. Barry is a brilliant leader and hugely respected across the business, and I have strong confidence that Diageo GB will thrive under his leadership and continue our commitment of brilliant execution.”
As these changes take place, Diageo is also announcing the appointment of Louise Ryan as the new Managing Director of Diageo Ireland.
