British Prime Minister David Cameron is backing Dubai to win the World Expo 2020 event.
In a statement, he said the UAE city deserved to win the decision of the 167 member nations of the Bureau International des Expositions (BIE), the organisers, who will cast their votes on November 27.
"I believe they should choose Dubai," Cameron said, saying it is a "city that shows how different cultures and peoples can converge behind common goals, living and working side by side".
The other cities still in the race to host the prestigious event are Sao Paulo in Brazil, Yekaterinburg in Russia and Izmir in Turkey.
Cameron added: "This is Dubai’s moment. As you approach Dubai its incredible skyline makes a stunning first impression. But as I discovered when I visited last year, you leave with a lasting impression of something far greater.
"In just 50 years, Dubai has been transformed from a small fishing and pearling town into one of the most cosmopolitan cities in the world. This is a city where you will hear Arabic, Urdu, Malayalam, Somali, Tagalog, Russian and English all being spoken and where more than 200 nationalities live and work."
He said holding Expo 2020 in Dubai will remind the world that the Middle East "is a region with potential and dynamism, a source of innovation for generations past, present and future".
Cameron is the latest big name to back Dubai's bid. Former US President Bill Clinton and London Mayor Boris Johnson also have publicly backed Dubai.
In the statement, the British PM said: "Dubai is a great business capital and its success rightly inspires people to see the potential of the region and to believe they can change their own countries for the better with vision, conviction and hard work. Dubai provides trading and transport hubs that connect the world. So an Expo in Dubai would be accessible to a far broader community."
