UK Prime Minister Rishi Sunak and his wife Akshata Murty are set to become the richest-ever occupants of 10 Downing Street. The couple's net worth is reported to be around $837 million, with a vast majority of it coming from Murty's Infosys stake. Notably, for the first time, the occupants of 10 Downing Street will be richer than Britain's monarch.
