Iranian cleric says UK embassy staff face trial

Jannati reiterated accusations by other senior Iranian figures that the West had plotted a so-called "velvet" revolution to undermine the Islamic Republic's establishment.

"They (the British) had ahead of time ... announced that in the election that is scheduled to take place in Iran there might be unrest and turmoil," Jannati said.

Jannati, who endorsed Ahmadinejad before the election, also hit out at the president's reformist opponents: "Isn't their approach an attempt to confront the (Islamic) establishment?"
