Power Players: What's next for Guinness owner Diageo?

Diageo, the company that owns Guinness, Smirnoff, Johnnie Walker and more than 200 drinks brands worldwide, has announced a major reset after a tough couple of years in which its profits have fallen and its share price has struggled. British businessman Sir Dave Lewis has been brought in to steer a turnaround, including a $1bn savings plan over the next three years. Known as "Drastic Dave" for cost-cutting at other companies, can he revive growth as more consumers drink less alcohol or switch from global brands to local ones?
