HAMPSHIRE businessman Jim Ratcliffe is £370m better off than last year, according to the new Sunday Times Rich List.

The authors have calculated that his fortune has increased from £150m to £520m over the past 12 months.

That includes his stake in Ineos, the Lyndhurst based chemicals company he founded in 1998, now reckoned to be worth £500m.

It makes Mr Ratcliffe the joint 145th richest person in Britain.

Top of the Rich List remains steel magnate Lakshmi Mittal, but his fortune has fallen by nearly £5bn in the past year, now standing at £17.5bn.

Another steel magnate, Alisher Usmanov, saw the biggest increase in wealth, moving up six places in the list to number two after adding £7.7bn to his fortune. Usmanov, 57, holds a 47 per cent stake in Mettaloinvest, Russia's largest iron ore producer.

The list, compiled by Philip Beresford, is based on identifiable wealth such as land, property, other assets such as art and racehorses, or significant shares in publicly quoted companies, and excludes bank accounts.
