The former WPP boss, who left abruptly in April, explained that all the holding companies are moving in the same direction – to become more integrated and added that the only difference is the speed in which they are moving.
“So I would say acceleration of that strategy, which I think by and large is pretty much what everyone else is doing, and as I say it’s not a question about where you’re going, the question is the speed.”
He also explained that it is not easy “flip the switch” from a business model that is very vertical to one that is client-orientated.
Earlier this month Roberto Quarta, WPP’s executive chairman, said that the company was dropping the concept of “horizonality”.
However, Sorrell went further today during an earlier stage appearance at Cannes, in which he claimed horizontality has been “obliterated” since his departure.
Sorrell, who has already set up a new company called S4 Capital, was interviewing the media writer Ken Auletta about his new book on the industry, Frenemies, which was reviewed earlier this month by Campaign‘s global head of media Gideon Spanier.
Quarta hinted to WPP shareholders at last week’s annual general meeting that the new chief executive is likely to come from the advertising and marketing world.
