The combined wealth of the richest 20 in the Northwest stands at £32.175bn this year with a record 11 billionaires among them. Only one of the top 20 has seen their wealth fall in the past year, while between them they are worth £2.724bn more than they were in 2017.
Robert Watts, the Compiler of The Sunday Times Rich List, said: “Our Northwest Rich List is again led by the Duke of Westminster, but wealth creation in the UK is increasingly a story of self-made - rather than inherited - wealth.
“Fred and Peter Done, the Issa Brothers and Henry Moser all started out with little, worked ferociously hard and now sit on ten-figure fortunes. That’s the big difference we’ve seen over the 30 editions of The Sunday Times Rich List - wealth creation is now a story of self-made men and women.
“Technology is also playing a bigger and bigger part in making fortunes. In Mahmud Kamani and Matt Moulding the Northwest has produced two of the country’s most digital savvy retailers. We expect their wealth to climb in the years ahead - although the 27-year-old duke may take some catching.”
