RIYADH (Reuters) - The relative youth and almost unprecedented power shared by the two heirs to the Saudi throne mean they are likely to dominate the kingdom's politics for decades, putting their pivotal relationship increasingly under scrutiny.
Crown Prince Mohammed bin Nayef, 56, and Deputy Crown Prince Mohammed bin Salman, 30, are next in line to succeed 79-year-old King Salman in ruling the world's top oil exporter, as it faces regional turmoil and low crude oil prices.
