Town chairman Dean Hoyle and his wife Janet are £4m poorer than they were this time last year.

But the Card Factory founders still rank among the top 20 richest people in Yorkshire with a shared fortune of £280m.

The Hoyles, who sold Card Factory in 2010 for a reported £350m, feature 12th on the list of Yorkshire’s richest people compiled by the Sunday Times. Their fortune is £4m lower than it was in 2014, although their ranking is unchanged.

A recent report revealed that Hoyle has pumped more than £37m into the John Smith’s Stadium club.

The Hoyles are one place above textile tycoon Alan Lewis, who is spearheading plans to turn Globe Mills at Slaithwaite into a centre for expanding and innovative businesses. Mr Lewis is ranked 13th in the list with £270m – unchanged from last year.

Grange Moor-born Malcolm Walker, chairman of Iceland Foods, is 17th on the list with a unchanged fortune of £215m while Morrisons founder Sir Ken Morrison and family are fifth with £733m – down by £167m on last year.

Brothers Eddie and Malcolm Healey are the richest people in Yorkshire, according to the 2015 Sunday Times Rich List – having seen their joint fortune grow by £200m in the past 12 months to £1.5bn.

Eddie, 77, sold his Parc Trostre retail park, near Llanelli in Wales, last year for £156m, having made £420m from the sale of the Meadowhall Centre at Sheffield some years ago. He also developed Centro, Europe’s largest shopping centre in Germany. His side of the family are now worth £950m, with his son, Mark, holding £250m of wind farm assets in Scotland.

Malcolm Healey, 70, made his money from building and selling Hygena Kitchens in Britain and America.

Lord Kirkham and family comes second on the list with a fortune of £1.15bn – based on the success of the DFS furniture retail chain. The group was sold for £400m in 2010, but a previous float and subsequent share sales generated £450m for the Kirkham family.

In 2012, Lord Kirkham helped to fund the takeover of the Iceland food group by Mr Walker and now has an 18.1% stake in the Iceland business.

Others to feature in the top 20 include Paul Sykes, who has bankrolled Ukip to the tune of more than £1.3m in the past year. The 71-year-old, who developed Meadowhall with Eddie Healey, is sixth on the list, having upped his fortune by £40m in the past year to £690m.

Hull City chairman Assem Allam, a major donor to the Labour Party, ranks 11th with a £20m gain in wealth in the past year taking him to £340m.
