6. The Clarke family
Net Worth: £500m
The Clarke family is a heavyweight landowner on Jersey, with chunks of St Helier and retail and pub sites across the island. The death in 2001 of patriarch Fred Clarke led to a refocusing of the business, with the aim of raising asset values.
According to the Sunday Times the Clarke family are Jersey’s largest private landowners, owning ‘tracts of St Helier and numerous retail outlets and pubs’.
Jane Clarke, the daughter of the former Constable of St Helier, Fred Clarke, is said to be leading the reorganisation of assets.
