Guy, George and Galen Jr Weston and family
Rank 2017

The giant Weston food and retailing operation, spanning Europe and North America, and its charitable arms remain firmly under family control. British brothers Guy, 56, and George, 53, are great-grandsons of Canadian baker George Weston, who founded the business in 1882.
   Guy chairs the £12.75bn, UK-based charity Garfield Weston Foundation, owner of 79.2% of Wittington Investments, the family’s main financial vehicle. In turn it controls Fortnum & Mason, Heal’s furniture stores and Associated British Foods (ABF) where George is chief executive. Their cousin, Dublin-born Galen Jr, 44, heads the £9bn Toronto-headquartered George Weston in which the family has a 63% stake. His father, Buckinghamshire-born Galen Sr, 76, is married to Dubliner Hilary, 75, a former model, and chairs London's Selfridges Group where their daughter Alannah, 45, is his deputy.
   Shares in ABF – which has brands including Kingsmill bread, Silver Spoon sugar and Ryvita, and low-cost fashion chain Primark as one of its main subsidiaries – have slipped in the past year. The Westons directly own a 20.8% stake worth £4.3bn.
