Ministry of Defence said:
Foreign Secretary William Hague has urged Iran to rethink its position. Commenting today, he said:
The UK went to Kazakhstan ready with our partners to negotiate in good faith with Iran.
Lengthy discussions took place on some issues, but a wide gap remains between the parties. Irans current position falls far short of what is needed to achieve a diplomatic breakthrough.
We look to Iran to consider carefully whether it wants to continue on its current course, and face increasing pressure and isolation from the international community, or to enter into meaningful negotiations.
