Rishi Sunak, the U.K.'s new prime minister, is richer than the royals

Rishi Sunak will become the wealthiest ever prime minister of the U.K., with his family's personal fortune surpassing even that of the royals. 

Sunak, 42, is breaking plenty of ground as he becomes the country's third premier in under two months. He's the U.K.'s youngest leader since 1812, as well as the first person of color to serve in the role. 

But Sunak's personal wealth is also grabbing outsized attention, especially as he takes the helm at a time the U.K. is facing an economic crisis he described as "profound" in his first address as prime minister. Sunak and his wife Akshata Murty are worth a combined $837 million (or 730 million pounds), according to the Sunday Times Rich List.
