According to report, Saudi Arabia's king has appointed his son Mohammed bin Salman as crown prince to replacing his nephew, Mohammed bin Nayef, as first in line to the throne.
King Salman's decree also means Prince Mohammed bin Salman, 31, will become deputy prime minister while continuing as defence minister.
Saudi state media says, Prince Mohammed bin Nayef, 57, has also been removed from his role as head of domestic security.
However, Prince Nayef has pledged allegiance to the new crown prince.
King Salman acceded to the throne in January 2015 after the death of his half-brother Abdullah bin Abdul Aziz.
Saudi Arabia has typically been ruled by kings in their 70s or 80s.
Prince Mohammed bin Salman's latest promotion, and his rapid ascent, is seen by the younger generation as a sign that things are changing.
BBC News stated that, His father King Salman is 81 and reportedly not in the best of health.
