We’ve been told by reliable sources that Mother has won the global creative business for Tanqueray. If you remember, we reported back in September that parent company Diageo launched a review of its gin brand. Since late October, we’ve been hearing that the New York/London-based shop beat out incumbent W+K and at least two other agencies in the review. Mother isn’t commenting either way on Tanqueray, which Wieden had handled since 2008. From what our spies tell us, Mother’s already in the process of doing work for the brand.
