When Saad Hariri's jet touched down at Riyadh on the evening of 3 November, the first thing he saw was a group of Saudi policemen surrounding the plane. When they came aboard, they confiscated his mobile phone and those of his bodyguards. Thus was Lebanon's prime minister silenced. It was a dramatic moment in tune with the soap-box drama played out across Saudi Arabia this past week: the house arrest of 11 princes ... and four ministers and scores of other former government lackeys. But back to Hariri. He was in a cabinet meeting in Beirut. Then he received a call, asking him to see King Salman of Saudi Arabia. Hariri ... set off at once. Out of the blue and to the total shock of Lebanese ministers, Hariri, reading from a written text, announced on Saturday on the Arabia television channel ... that he was resigning as prime minister of Lebanon. There were threats against his life, he said - though this was news to the security services in Beirut - and Hezbollah should be disarmed and wherever Iran interfered in the Middle East, there was chaos. These were not words that Hariri had ever used before. They were not, in other words, written by him. The Saudis had ordered the prime minister of Lebanon to resign and to read his own departure out loud from Riyadh. There will be no complaints from Washington or London, whose desire to share in the divvying up of Saudi Aramco (another of the crown prince's projects) will smother any thoughts of protest or warning.
