What Dubai World owns
DUBAI PORTS WORLD: World's fourth largest port operator whose investments include Port Of Tilbury in Essex, Southampton Container Terminals, Churchill Dock in Belgium and Port Of Djibouti in Africa.
NAKHEEL PROPERTIES: Developer of The Palm Jumeirah (including Atlantis, The Palm hotel), World Islands, Universe Islands and owns retired ocean liner QE II.
LEISURE CORP: Owns PGA European Tour venues such as Jumeirah Golf Estates and South Africa's Pearl Valley Golf Estates.
ISTITHMAR WORLD: Dubai World investment arm that owns American department store Barneys.
Dubai World spent the boom years hoovering up trophy assets around the world, including golf courses and hotels.
Their subsidiaries own everything from Barneys department store in the US to the QEII liner. These could now be sold off as Dubai's sheikhs scramble to raise cash.
The financial problems stem from a massive bubble in Dubai's housing market - and the Ј36billion debt taken on by Dubai World during their buying spree.
