The couple, both 44, have risen from 275th last year to 245th with an estimated wealth of GBP 651 million, making them the “wealthiest people to call 10 Downing Street home”.

Murty’s earnings are said to far exceed that of her husband as financial statements published in February are quoted to say Sunak made GBP 2.2 million in 2022-23 compared to Murty’s estimated GBP 13 million in dividends over the past year.

“The couple’s most valued asset is Murty’s shareholding in Infosys, a Bangalore-based IT company co-founded by Murty’s father [Narayan Murthy],” reads the newspaper’s analysis.

“Over the past year, the shares have grown in value by GBP 108.8 million to nearly GBP 590 million. The latest annual report suggests that Murty received about GBP 13 million in dividends during that time — adding to the more than a million pounds she has been paid in previous years. She is poised to receive another GBP 10.5 million this year,” it notes.

The annual compilation of Britain’s wealthiest families is once again topped by the Indian-origin Hinduja family, who saw their wealth increase over the past year to hit GBP 37.196 billion in the wake of the opening of their brand-new luxury OWO Hotel in the heart of London.

The UK-based family’s group of companies, headed by chairman G.P. Hinduja, operates in 48 countries and across several sectors – automotive, oil and speciality chemicals, banking and finance, IT, cyber security, healthcare, trading, infrastructure project development, media and entertainment, power, and real estate.

“It has been a year of expansion through acquisition for the group, made possible in part by growing stock market valuations of the family’s main listed holdings, which have risen to a total of GBP 8.7 billion,” reads the newspaper’s analysis.

The top 10 of the 2024 ‘Sunday Times Rich List’ sees another set of India-born brothers, David and Simon Reuben, build on their wealth to rise to third place from last year’s fourth, with a fortune estimated at around GBP 24.977 billion.

At No. 8 is NRI tycoon of ArcelorMittal steelworks Lakshmi N. Mittal, who slips two places from last year with an estimated GBP 14.921 billion, followed by Vedanta Resources’ industrialist Anil Agarwal at No. 23 with an estimated GBP 7 billion – down one rank from 2023.

Other Indian-origin billionaires on the 2024 list include textiles entrepreneur Prakash Lohia at No. 30 with an estimated GBP 6.23 billion; retail majors Mohsin and Zuber Issa at No. 39 with GBP 5 billion; and pharma chiefs Navin and Varsha Engineer at 58 with GBP 3 billion.

Among the top 100 richest Britons are brothers Simon, Bobby and Robin Arora at No. 65 with GBP 2.682 billion and leading NRI industrialist Lord Swraj Paul and family ranked 67th with an estimated wealth of GBP 2.6 billion – same as last year.

Fashion industrialist Sunder Genomal, a new entrant in 2023, is ranked 77th with a fortune estimated at GBP 2.214 billion, with hoteliers Jasminder Singh and family coming in at 83 with GBP 2.001 billion.

On the whole, the 36th edition of the rich list reveals the largest fall in billionaires in its history – down from a peak of 177 in 2022 to 165 this year.

“This year’s Sunday Times Rich List suggests Britain’s billionaire boom has come to an end. Many of our home-grown entrepreneurs have seen their fortunes fall, and some of the global super-rich who came here are moving away,” said the list’s compiler, Robert Watts.

However, moving from millionaire to billionaire on the tally is former Beatle Sir Paul McCartney – now the first UK musician to achieve that status after boosting his wealth by GBP 50 million over last year.
