Retailers have tumbled down this year’s The Sunday Times Rich List as turbulent market conditions take a toll on personal fortunes.

Sports Direct founder Mike Ashley and former BHS owner Sir Philip Green are among those who have fallen down the list, following scandals enveloping their respective businesses.

Ashley, who was dragged through a parliamentary inquiry last summer over alleged employment practices at Sports Direct’s Shirebrook warehouse, slipped nine places to 54.

He is now said to be worth £2.16bn, down £270m from last year.

Arcadia tycoon Green and his wife Tina dropped 12 places to 41. The Sunday Times said the couple’s collective fortune decreased £433m to £2.78bn.

South African retail mogul Christo Wiese, who rocketed into Rich List last year after acquiring New Look for £780m, fell two places to 24 this time around. However, his fortune increased £290m to £4.6bn.

Carphone Warehouse co-founder Si Charles Dunstone was among the biggest fallers in this year’s list, slumping 55 places to 137.

His personal worth is said to have been slashed by £354m over the past year to £946m.

The Range owner Chris Dawson and his wife Sarah slipped nine places to 67, despite their combined worth increasing £150m to £1.9bn.

Fellow discount store operators Simon, Bobby and Robin Arora, who founded B&M, dropped 10 places to 65, as their combined fortune remained flat at £1.9bn.

The Hut Group co-founder Matt Moulding was one of the few retail risers, rocketing almost 600 places to 345.

Moulding, who has a 23% stake in the business, is now said to be worth £345m, up £240m from 2016.

Asos founder Nick Robertson also climbed more than 300 places to 379, despite selling £70m of shares in the etailer to fund a divorce settlement.

Robertson still holds a 6.6% stake in the business, accounting for £283m of his £303m fortune.

Guy, George and Galen Weston and family, which owns Primark parent company Associated British Foods, were again the highest-ranked retailers on the list, although they fell three places to seventh after their estimated wealth dropped £500m to £10.5bn.

Brothers Sri and Gopi Hinduja, who invest in property, healthcare and oil and gas, topped the list with a combined fortune of £16.2bn – up £3.2bn from a year ago.
