The largest giant observation wheel in the world has opened in Singapore.

The Singapore Flyer stands at around 165 metres (541 feet) tall, dwarfing the London Eye which is 135 metres (442 feet) high.

At the official opening ceremony, the country's Prime Minister Lee Hsien Loong told the crowd the wheel was set to become "one of the busiest Flyers in the world".

Florian Bollen, the chairman of Singapore Flyer, said the wheel is built differently from the London Eye.
