Rank 2017

Thompson, 81, and his wife Patricia, 77, saved Cheveley Park Stud from bankruptcy 40 years ago and now Newmarket's oldest horse breeding farm is thriving. Former Smithfield meat trader Thompson made his wealth through his food group Hillsdown, selling half his stake for £145m in 1987 and the rest for a similar sum later. There are assets exceeding £225m in the latest accounts of the couple’s businesses and another £100m in those of the family charity, which gave away £4.55m in 2015-16.
