The billionaire Hinduja brothers have been named as the wealthiest people in the UK for a third time, according to the Sunday Times Rich List.

Sri and Gopi Hinduja saw their fortune increase by £1.356bn in the last year to £22bn, the paper estimates.

Meanwhile, chemicals firm founder Sir Jim Ratcliffe, who topped last year's list, has slipped to third place.

And Valerie Moran becomes the first black female entrepreneur ever to make the paper's Rich List.

Family business the Hinduja Group was founded in Mumbai in 1914, and now has interests around the world including in oil and gas, banking, IT and property.

British citizens Sri, 83, and Gopi, 79, who are based in London, are two of the four brothers controlling the empire.

Among the properties they own is the Old War Office in Whitehall, which they hope to reopen as a luxury hotel.

The two brothers topped the newspaper list in 2014 and in 2017.

Robert Watts, who compiled this year's list, said: "On the face of it this looks like a bumper year for the super-rich, with record wealth, more billionaires and the entry level rising to £120m.

"But many of the rich are nursing big losses after a year of turbulence on the stock market and political deadlock in Westminster.

"Technology is making and breaking fortunes. We are finding young entrepreneurs making vast sums of money from online fashion retail, dating apps and creating YouTube videos."

He added that online shopping "continues to have a profound effect" on UK high streets, adding that well known retailers "are seeing their fortunes smashed by this seismic change".
