It’s been another busy week on The Grocer.

The big news was the appointment of Sir Dave Lewis as the new CEO of Diageo. Lewis has nothing to prove after an outstanding career but it’s fascinating to consider why he’s chosen, at the age of 60, to take on another CEO role, after five years in non-exec roles. One wonders too if he is motivated by the fact he was overlooked for the role (in favour of the late Ivan Menezes) in 2013. It’s certainly a mouth-watering prospect as to what he might do in the role. As this excellent piece from drinks editor James Beeson points out, Lewis’s 30 years of brand and category experience at Unilever will probably be more valuable than his time at Tesco. The latter role was more high profile, political and public facing, whereas at Diageo Lewis is likely to do his most important work in the field – doubtless racking up a lot of airmiles as he familiarises himself with Diageo’s global operations, its leadership teams, its myriad brands and the unique attributes of the on-trade, which will be a new challenge.
