The retired chairman of Bradford-based Morrisons, Sir Ken Morrison, has retained his place at the top of Yorkshire’s Rich List.

Although Sir Ken has seen his wealth drop by £70m in the last year, he is one of two billionaires in the region, according to the latest survey, which is published tomorrow.

Morrisons has seen a 31 per cent surge in profits in the past year. The Morrison family stake in the business is worth £1,405m this year and proceeds from dividends and share sales have been included in the calculation.

Sir Ken has retired as chairman after 56 years in the supermarket business.

The overall wealth of Yorkshire’s top ten in new edition of The Sunday Times Rich List has increased by nine per cent, rising £570m from £6,339m to £6,909m, mirroring the recovery in fortunes of the richest seen across the UK.

In second place are Eddie and Malcolm Healey, the brothers who have made their millions from property deals and kitchens, while David Hood, 62, co-founder of Saltaire electronics firm Pace, is the 13th richest, with £260m, up from £220m last year.

In 15th is Jack Tordoff, 74, whose fortune has risen by 110 per cent from £100m to £210m in the last year.

Mr Tordoff, who is honorary life president of Bradford City, joined his father’s motor business in 1958 when it had just four staff and was instrumental in creating the JCT600 empire.
