NEW YORK Hill & Knowlton will launch a subsidiary company in east Africa next month. The Hill & Knowlton East Africa Ltd., is a joint venture with Scangroup Limited. The company will be headquartered in Nairobi, Kenya, and will cover that country, Uganda, and Tanzania. George Godsal, currently director of corporate communications at H&K's London office, will run the new entity. He will report to Dave Robinson, CEO of H&K Middle East and Africa. Scangroup's existing business and consulting work will operate under the joint venture and H&K East Africa brand. The launch follows last year's acquisition of 27.5% of Scangroup by WPP, H&K's holding company.
