Seven Sunday Times Rich List billionaires have links to the Channel Islands, with the Barclay family still ranked the wealthiest.
The billionaire Telegraph owners have seen their fortune grow by more than £200 million in the past 12 months.
87 year old Frederick lives on Brecqou. His twin brother David died in 2021. The family has been involved in lengthy court battles in recent years.
Robert Watts who compiles the list says their wealth still exceeds £6 billion.
"Their retail businesses - Very.co.uk and Littlewoods - had a good pandemic. They managed to grow their profits to £132 million. There is talk that they will float that business for as much as £4bn... and their Telegraph group remain a valuable asset.
Although there was a bust-up between different parts of the family - Sir Frederick's end and the late Sir David's children - we do aggregate family wealth."
