London [UK], Prime Minister Rishi Sunak and his wife, Akshat Murthy's wealth has seen a significant rise, increasing by more than £120 million in the last year, thus taking their combined wealth to £651 million, UK The latest annual Sunday Times Rich List has revealed a huge increase in the wealth of Britain's billionaires despite tough economic conditions, marking the "end" of a wide-ranging surge in the number of billionaires, UK-based broadcasting network ITV reported. Despite the downturn in the wider UK billionaire landscape due to the challenging economic situation, Sunak and Murthy have seen their wealth rise significantly, now standing at £651 million compared to £52 million last year. This impressive growth can be primarily attributed to Murthy's ownership stake in the prestigious Indian IT giant Infosys.

Despite these individual successes, the overall landscape for British billionaires is changing. The number of billionaires in Britain has seen a decline for the third consecutive year, falling from a peak of 177 in 2022 to 165 this year.
