Tesco replaces CEO as profit slides

Dave Lewis, who as head of Unilever’s personal-care unit has led the expansion of the British-Dutch firm’s fastest-growing business, will succeed 54-year-old Clarke on October 1, the supermarket operator said.
Clarke is being replaced after struggling to stem the march of discounters Aldi and Lidl at one end of the UK grocery market, and upscale chains such as Waitrose at the other.
