Prince Ahmad bin Abdulaziz flew back to Riyadh from London on Tuesday, according to three Saudi sources close to the prince cited by 'The New York Times', in what some analysts are calling a potential challenge to the authority of Saudi Arabia's de-facto ruler Crown Prince Mohammed bin Salman.
One of the most senior members of the royal family, Prince Ahmad - who has been living in the United Kingdom - is said to have agreed to return to Riyadh only after receiving security assurances from the UK and United States.
The reports say the prince had been afraid to return home after publicly challenging bin Salman on several occasions.
