Claire Enders was quoted in an article on Sir Martin Sorrell, who is plotting his return. Last week, he announced the reverse takeover of another small listed vehicle – to be renamed S4 Capital in reference to four generations of the Sorrell family – fronting £40m of his own money to rebuild his empire. Claire says that like these other business leaders, whether he succeeds or fails, Sorrell cannot step back “He cannot change his character and be someone who retires: it is not his way”. She adds “There are 33 years [spent at the helm of WPP] he can’t have again – and whether he has the same judgment is another matter – but Sorrell is a workaholic and incredibly motivated by achievement”. Claire points out that in the media industry, gerontocracies are strikingly common: Rupert Murdoch is 87, Liberty Global owner John Malone is 77, serial entrepreneur Barry Diller is 76 and Viacom’s Sumner Redstone, aged 95, is still hanging in there – albeit leaning heavily on his daughter Shari. With Sorrell’s telephone book, she reckons few would bet against him. “He has fantastic contacts with every major chief executive on the planet: he can get a meeting with anyone,” she says. “If anyone can build a business, he can”. Claire believes that Sorrell may even look to make the ultimate final deal – bidding for parts of the WPP empire that he created, such as data business Kantar.
