"Foreign leaders visiting King Salman of Saudi Arabia have noticed that there is a large flower display positioned just in front of where the 80-year-old monarch sits. On closer investigation, the visitors realised that the purpose of the flowers is to conceal a computer which acts as a teleprompter, enabling the King to appear capable of carrying on a coherent conversation about important issues.
One visiting US delegation meeting with King Salman recently observed a different method of convincing visitors – or at least television viewers watching the encounter – that he can deal with the escalating crises facing Saudi Arabia. The king did not look at the group but at a giant television screen hanging from the ceiling of the room on which was appearing prompts." (thanks Basim)
