King Salman gives Saudi a political makeover

Saudi Arabia's new king did not wait long to makeover the monarchy to suit his fashion. As part of a wide cabinet overhaul, King Salman sidelined his half-brother, the former crown prince, replacing him with his nephew. He also appointed his own son deputy crown prince and chose the Saudi ambassador to the US, a non-royal, to be the country's new foreign minister. For a country not known for big and sudden changes, the number and range of decisions taken by King Salman in his first 100 days is new for Saudi Arabia. So what does this all mean for the future of the monarchy?
