P&G is set to hand the UK work held by Fleishman-Hillard to Hill+Knowlton Strategies. It already uses the agency for the disposable nappy brand's EMEA activities.
The news follows last month's revelation that P&G had moved global PR duties for its Vicks brand to MSLGroup, which previously handled only European activities.
Last month, P&G cut its profit forecast for the year, against a backdrop of sluggish economic growth in the West, higher costs for raw materials and internal restructuring.
P&G brand PR manager Catherine McMahon confirmed the account shift but declined to comment on further consolidation plans.
Fleishman-Hillard will continue to work on the Pampers account until the summer.
Meanwhile, the agency has won the PR and social media account for Symington's foods, which includes Ragu.
