martin sorrellWPP reported PR and public affairs revenues climbed 8.8% in the first half of 2016 to $661.1M while revenues across the agency conglomerate saw a 5.2% rise to nearly $9.4B.

Despite the gains, profit plunged 43.9% to $609.5M over the same period of 2015 as the Martin Sorrell-led company took a large write-down on its comScore investment amid an accounting probe there and faced comparison to an extraordinary first half profit in 2015.

The results were better than expected and WPP raised its forecast for full-year revenue growth.

Coming out of the first half, WPP said all regions and sectors, except data investment management, were positive in July, and showed a "similar relative pattern to the first half," singling out advertising, media investment management, PR and public affairs and specialist communications as "up strongly."

The company said a plunge in Britain's pound sterling after the Brexit vote may have supported a recovery in that market.
