Newton, who left InBev last November to travel, will lead the consumer marketing strategy and report to Andrew Carter, marketing director for Bacardi Brown-Forman Brands.
During his tenure at InBev, Newton was responsible for brands including Stella Artois, Beck's and Boddingtons.
Previously, Newton was head of brand marketing at Nestle Rowntree. He had been tipped to succeed then-marketing director Andrew Harrison. However, he was a casualty of the restructure that ensued when Chris White was drafted in as managing director in February 2004.
