Buyers have been alerted to the prospect of an Interpublic sell-off by the maximum value proposal put forward by the shareholder Charles Miller. It calls for Interpublic to be broken up and its component parts sold off.

Interpublic said: "Selling any of our assets at this early stage of our turnaround makes no sense."
