Rank 2017

In a boon for society pages across several continents, the Colombian-American billionaire Alejandro Santo Domingo, 40, married British blue-blood Lady Charlotte Wellesley, 26, in a 16th-century Spanish church last May. Jostling for pew space were members of the international elite including the Duchess of Cornwall, Spain's former king Juan Carlos I, Monaco royal Andrea Casiraghi and the army officer turned singer James Blunt.
   New York-based Santo Domingo is the Harvard-educated scion of the Bavaria brewery in Colombia, sold by his father Julio Mario (who died in 2011) in 2005 for a 15% stake in SABMiller, then the world’s second-largest brewer. The stake is the largest in a diverse portfolio of companies that make up the privately held Santo Domingo Group.
   With his square jaw, luxuriant hair, philanthropic leanings and £3.2bn fortune, Santo Domingo was the prize of Manhattan’s socialite dating scene. But it took English rose Wellesley, fourth daughter of the 9th Duke of Wellington and Princess Antonia of Prussia, to capture his heart.
   With an Oxford degree in archaeology and anthropology, Wellesley became an assistant to the Peruvian fashion and portrait photographer Mario Testino. Her Twitter username is CAWblimey and she sailed in the notoriously tough Fastnet Race in 2011. For her wedding breakfast, Wellesley eschewed her family’s 2,743-acre seat, Stratfield Saye in Hampshire, in favour of its 2,359-acre pile in Granada, gifted to the first Duke of Wellington for supporting the Spanish against Napoleon’s France.
