Six big powers meet Iran to discuss its contentious nuclear programme

• EFFORTS to curtail Iran’s nuclear programme will gather pace in Geneva on Thursday October 1st. The six countries negotiating with Iran—America, Britain, France, Russia, China and Germany—want Iran to come clean about its nuclear ambitions and to cease enriching uranium, which could be used to construct an atomic bomb. The last such talks, in 2008, broke down after Iran refused to admit that enrichment was going on. This time America has threatened “crippling sanctions” if talks collapse. Russia, usually indulgent of Iran, may be willing to support sanctions, especially after revelations that Iran has been secretly building a new enrichment plant.
