Topping the list in the

Sir James Dyson is the richest person in the southwest, according to The 2015 Sunday Times Rich List, to be published this Sunday, April 26. The 128-page special edition of The Sunday Times Magazine reveals the wealth of the 1,000 richest people in Britain.

Dyson’s business, headquartered in Malmesbury, goes from strength to strength and is now worth £3bn. It took Dyson 15 years to get his original bagless vacuum cleaner on the market but he has no such problems today. His latest product, the Dyson 360 Eye robot, was recently unveiled and engineers are working on technology that could double the life of smartphone batteries. Keen to encourage the next generation of design engineers, Dyson, 67, is pouring money into higher education. Last month, he gave £12m to Imperial College London to fund the Dyson School of Design Engineering, while last year he gave £8m to the University of Cambridge. In addition to his £3bn business, Dyson has land holdings amounting to 25,000 acres and an 18th-century manor house, Dodington Park, in Gloucestershire. He is worth £3,500m in all.

Peter Hargreaves and Steve Lansdown, at second and fourth respectively in the southwest Rich List, have both seen their overall wealth decline in the past 12 months. Hargreaves, 68, is down £496m and Lansdown down £157m as a result of a decline in the overall value of the financial group they founded together. Hargreaves Lansdown is worth close to £5.6bn with Hargreaves’ current stake adding up to £1,824m, and Lansdown holding £902m-worth of the stock. Lansdown, 62, formed Bristol Sport, bringing together Bristol City football club, newly promoted to the Championship, and other sports, including Bristol Rugby, the city’s rugby union side. His son, Jon, is the managing director.

Bisecting the Hargreaves Lansdown duo is Chris Dawson, who has added £370m to his fortune in the past 12 months off the back of the continued success of his Devon-based home-and-garden discount chain, The Range. A former market trader, Dawson opened his 100th store in Plymouth two months ago. There are now 110 stores within the business, which is valued at £1.5bn. Other assets and property lift Dawson to £1,650m.

In a good year for the southwest, which has seen 12 of the top 20 wealthiest gain in value in the past 12 months, Julian Dunkerton, co-founder of the SuperGroup fashion retailer (which trades on the high street as Superdry) has seen the biggest reverse in his fortune. The business is now valued at £753m, compared with £1.3bn a year ago. Dunkerton has seen his stake in the business shrink from £445m to £242m. Taking into account previous share sales, he is worth £263m, down £215m on last year.
