Stockwell was previously head of consumer at Firefly, and prior to that was consumer director at Cohn & Wolfe.
His experience incorporates consumer goods, leisure, retail to technology, having led teams on clients including Virgin, Diageo, London 2012, Coca-Cola, LG and Freesat.
At Citigate, Stockwell will work alongside Steve Marinker, consumer practice director, in building the agency's portfolio in the consumer sector.
Stockwell said: ‘Citigate has unrivalled knowledge of the business, financial and corporate agenda and effectively combines this with understanding consumer audiences and channels. As a result the agency develops high impact consumer campaigns which build brands and deliver business objectives.... my aim is to help build on that work and strengthen the agency's reputation in consumer PR.'
