Dubai government developer Nakheel hopes to sell a penthouse in Donald Trump’s towers on Dubai’s first artificial island for more than $30m, which would smash the emirate’s record for its most expensive apartment.

The two towers of the Trump International Hotel & Tower, scheduled for completion in 2011, will form the gateway to Palm Jumeirah, the offshore development that will co-host a permanent residence for the Cirque du Soleil and the retired QE2 cruise liner, along with hotels, apartments and villas.
