In 2011, he was estimated to be worth £12billion by Forbes. His family is believed to have a fortune of £123bn.

He owns a £400million yacht - that Azzam - which boasts of 50 suites, gym, pool. golf training room and can accommodate more than 100 people.

It was said to be the longest yacht in the world at 590 feet when it hit the seas in 2013.

It was eclipsed in 2019 by just three metres by the research and expedition vessel REV Ocean.

The Burj Khalifa, the world's tallest building, was originally called the Burj Dubai but was renamed in his honour after Abu Dhabi helped pay £8.21billion in Dubai's debts.

He is expected to be succeeded as ruler of Abu Dhabi by his half-brother Crown Prince Sheikh Mohammed bin Zayed al-Nahyan.

Mohammed bin Zayed has been the de facto ruler of the UAE after Khalifa suffered a stroke in 2014.

He leaves behind his wife Shamsa bint Suhail Al Mazrouei and eight children: Sultan, Mohammed, Shamma, Salama, Osha, Sheikha, Lateefa and Mouza.
