Ford Motor Company will open up some areas of its WPP-managed business to other bidders.

Details about which sections will be open for bidding remain scant.

Speaking on the announcement, a WPP spokesperson said: “GTB/WPP has been informed that its creative business with Ford is up for review.”

“WPP/GTB is the most capable, passionate, informed and dedicated partner to build Ford’s vision of the future.”

“We will be enthusiastically responding to Ford’s request for review in the days ahead.”

The move follows WPP CEO Martin Sorell’s departure from the ad giant last week.

In other WPP news, speculation is growing that Jerry Buhlmann, the man who looks after Japan’s Denstu Aegis division, could be a favourite to take over the company.

Another possible candidate is Andrew Robertson, who heads up BBDO.

Neither has made a comment on the rumours.

Sorrell’s resignation was the result of an investigation into the CEO’s apparent “personal misconduct”, a claim he vehemently denies.

Following his departure, a staff memo regarding his resignation was leaked to the public.

“We have weathered difficult storms in the past. And our highly talented people have always won through, always.”

“Nobody, either direct competitors or newly-minted ones can beat the WPP team, as long as you work closely together, whether by client and/or country or digitally,” one section read.
