Riyadh - The heir to the throne in Saudi Arabia has consolidated his hold on power with a major purge of the kingdom's political and business leadership. A new anti-corruption body, headed by Crown Prince Mohammed bin Salman, detained 11 princes, four sitting ministers and dozens of ex-ministers. Prince Alwaleed bin Talal, a billionaire with investments in Twitter and Apple, is among those held. Separately King Salman replaced the national guard and the navy chiefs. The new anti-corruption committee has the power to issue arrest warrants and travel bans. Attorney General Sheikh Saud al-Mojeb said the status of the detainees would not influence "the firm and fair application of justice", AFP news agency reports. Saudi broadcaster Al-Arabiya said fresh investigations had been launched into the 2009 Jeddah floods and the outbreak of the Mers virus which emerged in Saudi Arabia in 2012 - but analysts see the detentions as a clear move by the crown prince to strengthen his power base.(FA)
