WHO IS DAVE LEWIS? Known as "Drastic Dave" for his bold creative strategies and strict hand at keeping costs low, Lewis helmed the UK launch of Dove, a personal care brand, along with other successful campaigns. Lewis hung up his boots at Unilever in 2014 to head Tesco, one of Britain's biggest retailers, as its first boss to come from outside the company. Lewis put Tesco back on track after an accounting scandal and refocused the group on its home market. A graduate of Nottingham Trent University with a bachelor's degree in business studies, Lewis was also knighted in 2021 in recognition of his contribution to business and the food industry in the UK. He hails from Yorkshire. CHALLENGES AS DIAGEO'S CEO: Lewis will take over the world's most influential spirits maker at a time when the company is struggling with weak sales in a market muddled by tariffs, high costs and changing consumer preferences. The company cut its sales and profit forecasts last week as consumer confidence remains low in the U.S. and China, two of its most crucial markets. The tougher industry backdrop is driving Diageo's attempt to cut costs and sell assets as the drinks industry faces cooling post-pandemic demand.
