"We cannot and will not succumb to the temptation of sealing a deal at any price, but we will remain steadfast in pursuit of a comprehensive agreement which respects the clear principle that Iran must not be able to develop a nuclear weapons capability," Hammond said at the House of Commons.
"The negotiations with Iran are tough and complex, but a comprehensive agreement would bring enormous benefits to all parties," Hammond stated, explaining that it would mean the "reintegration into the international community" for Iran, and "a considerable advance for regional and global security" for the international community.
The West has been accusing Iran of developing nuclear weapons under the guise of civilian activities, though this has been repeatedly denied by officials in Tehran, who claim the country's nuclear development is peaceful in nature and aimed at satisfying Iran's energy needs.
