A UK court has ordered Sheikh Mohammed bin Rashid al-Maktoum, Dubai's ruler, to pay his ex-wife Princess Haya bint al-Hussein over £500 million.
It is one of the largest divorce settlements ever ruled on by a British court.
The cost of keeping Princess Haya bint al-Hussain safe for life and the upkeep of the couple's children will be covered in the settlement.

The Sheikh will have to hand over more than £250m in the next three months.
Mr Justice Moor, in his judgement, ruled that the most significant threat facing Princess Haya and her two children comes from the Sheikh "himself" rather than from "outside sources."
In October the court heard that the Sheikh had used "Pegasus software, which is only available to governments," to spy on the Princess.
Justice Moor's judgment referenced evidence that the Princess paid four members of staff more than £6m not to tell anyone about the affair she had with one of them.
The court heard Princess Haya was 'terrified' after receiving a threatening phone call from the Sheikh on the matter of the affair.
"The court has now made its ruling on finances and he does not intend to comment further," said a spokesperson for the Sheikh in a statement.
"He asks that the media respect the privacy of his children and do not intrude into their lives in the UK."
The High Court decided that Sheikh Mohammed employed his "immense wealth, political power and international influence" to intimidate Princess Haya.
The settlement marks the end of a two-year legal battle between the divorced royal couple.
