WPP investors voted against the remuneration packages of directors, including CEO Martin Sorrell, as the revolt over executive pay spread to the world’s biggest advertising agency.

In a nonbinding vote, 60 percent of investors in WPP voted against the proposed pay, which included a 56 percent increase for Sorrell. The company will now approach shareholders to discuss options and reconcile the two sides, said one person with knowledge of the matter, declining to be named as the plan is not public.
