Sorrell is Lowe in Amex’s estimation

Most people would confuse Frank Lowe with Martin Sorrell at their peril. The staff of the Lowell Hotel in the heart of Manhattan evidently enjoy living dangerously.

At 4.30am, the insomniac Sorrell was making yet another international phone call when what should slip under his door but Lowe’s faxed American Express bill; in an envelope addressed to Mrs Lowe, who happened to be staying in the same hotel.

Sorrell is coy about the contents, but hints at some interesting items.

“I didn’t send the fax to Phil Geier [Lowe’s boss at IPG],” he says. “But I’m glad to see Frank is using Amex.” Amex is one of WPP’s biggest clients.
