5. Eddie & Sol Zakay
£1,500m
Topland Group
2008: £1,500m (No change)
Sol Zakay, the billionaire property tycoon, has quit Britain after the introduction of a 50% tax rate on high earners.
He recently resigned as chairman and chief executive officer of Topland Group and the UK Topland companies to join the group's offshore parent company as a consultant.
The Topland business, built with his brother Eddie, will remain in the UK. Eddie, 59, is to become chairman of the UK businesses and stay in England.
Sol, 57, will concentrate on finding global opportunities for the Topland group. In the summer, Topland was among the underbidders for an £800m UK portfolio put up for sale by Aviva Investors.
The property crash has not cramped the style of the Zakay brothers. Late in 2008 they bought a 15-strong portfolio from a Spanish retailer for £289m. But the main Zakay company in Britain, Topland Group, nearly doubled its losses in the year to May 2008 from £16.7m to £29m.
The brothers launched their business during the 1980s property boom before expanding into the American and Middle Eastern markets. They made much of their fortune in the UK through a series of multi-million-pound deals with chains such as Marks & Spencer and Tesco.
The Zakays have around 157 directorships and their total portfolio worldwide is valued at around £4bn. In all, after stripping out borrowings, the Zakay family should still be worth £1.5bn.
