After three years throwing jabs at erstwhile rivals, Sir Martin Sorrell finally admits he couldn’t change WPP fast enough. He says public company structures doom the holdcos to failure, hobbling their ability to change direction at the requisite speed. Meanwhile, he blasts WPP AUNZ’s attempts to effect change, suggesting the London-controlled group will remain ‘’rudderless’’ if it fails to appoint a strong parochial leader. Naturally, everyone else gets a poke too as Sorrell graces Mi3’s 100th podcast, which probably isn’t suitable for the thin skinned.
