Kirsten and Jorn Rausing

Rank 2017

The Queen (qv) appointed Kirsten Rausing, 64, deputy lieutenant of Suffolk in January, a role that involves assisting with royal visits to the county. Swede Rausing should have plenty to talk to Her Majesty about as both share a keen interest in horseracing. A member of the Jockey Club, she owns two Suffolk stud farms and is a passionate turf enthusiast. In 1994 she became a non-executive director of the British Bloodstock Agency, which buys and sells racehorses on behalf of wealthy clients, and has since become its joint owner. She also owns Ireland’s Staffordstown Stud in Co Meath.
   The Rausings’ fortune derives from Sweden’s Tetra Laval packaging group, owned by her family, including brothers Jorn, 57, and Finn, 61. The Swiss-based business was built into a huge multinational by their late father Gad – whose wife Birgit still retains a large stake in the operation – and his brother Hans (qv).
   Jorn, who lives in Surrey, also invests in his own right, putting £26.5m into online supermarket retailer Ocado, with his holding worth £182m. A strong performance by Tetra Laval, including sales of more than £10bn in 2015-16, underpins a valuation for the two siblings of £9.66bn, up nearly £1bn on last year.
