Dubai developer Nakheel – the company that created man-made islands in the shapes of a palm tree and the world – said the structure will be the centre-piece of an inner-city harbour set to become the emirate’s new, unofficial capital.

Towering over the Burj Dubai, the Nakheel Tower is planned to be the tallest building on the planet.
