As the tallest building in the world opened to great fanfair in Dubai yesterday, the struggling emirate was well aware that it owed a big thank you to its oil rich neighbour. The thanks came in the form of a naming ceremony, Dubai's ruler renamed the previously-known Burj Dubai the Burj Khalifa. Just last month the tower's namesake and leader of Abu Dhabi, Sheikh Khalifa bin Zayed Al Nahayan, bailed out indebted Dubai to the tune of $10bn - £6.13bn.
Dubai ruler Sheikh Mohammed Bin Rashid al-Maktoum led the official opening which saw VIPs able to access the observation deck on the 124th floor.
