Earlier this year, the veteran lost a legal case against MDK, now a WPP-owned shell company, which sued him and ex-CEO Michael Rose for poaching staff and clients. It is believed that de Kretser will appeal the decision by Singapore’s High Court.
De Kretser declined to comment on the legal action but said that the book will reveal the “inner workings of the WPP Group”.
He added: “This book hopefully will clarify, simplify and add a little chilli padi to the world of public relations.”
