Iran will today come under mounting pressure to reveal the true nature of its nuclear programme during talks in Geneva.The five permanent UN Security Council members, the UK, China, France, Russia and the United States plus Germany are contemplating tightening sanctions on Iran. The International Atomic Energy Agency has accused Iran of being on the wrong side of the law for failing to declare the existence of a second uranium enrichment plant in Qom. White House spokesman Robert Gibbs said: “The world will know, the beginnings of which tomorrow, whether the Iranians are willing to step up to that, whether they are going to continue to do the types of things and hide parts of their programme like they have done and then, I think, that will show the world what the intention is.” Despite being accused of breaking a transparency law by failing to declare the Qom plant’s construction, Tehran says its nuclear programme is not up for discussion. Iran insists all its nuclear facilities are for peaceful energy purposes and denies claims it is seeking nuclear weapons capability. Showing no sign of willingness to compromise. Iranian President Mahmoud Ahmadinejad said Tehran is looking for a changed approach from the West.
