Dubai bids to host World Expo 2020

Dubai has been trying to impress the judges who will decide next month who will host the World Expo in 2020.

Held every five years, expos see hundreds of countries using pavilions to show off the latest in architecture and technology.

Dubai is up against three other cities: Sao Paulo in Brazil; Yekaterinburg in Russia and Izmir in Turkey.

Many think Dubai is the favourite to get the event as Howard Johnson reports.
