The 'ground is prepared' for direct talks between Iran and the United States over the situation in war-ravaged Iraq, former Iranian president Mohammad Khatami said on British television on Tuesday.
Khatami also said that he did not think that Iran was intervening militarily in neighbouring Iraq, despite suspicions that the country was arming insurgents in the south.
Asked whether Iran was prepared to talk directly to the United States about what to do next in Iraq, Khatami told Channel Four: "Through an international activity under the auspicious supervision of the United Nations, I think the ground is prepared to do so."
Khatami was in Britain to receive an honorary degree from the University of St Andrews in Scotland.
He is also set to address the Royal Institute of International Affairs think-tank in London and academics at Oxford University during a three-day visit.
"I am strongly of the opinion that Iran doesn't have any military intervention in Iraq," he told Channel Four.
"The security of Iraq is quite important to us, because anything that would contribute to security in Iraq or add to the violence among the Shia and Sunnis and instability, the first one that would lose would be Iran of course."
The former president also said that Iran was not developing nuclear weapons, as debate continues over the country's refusal to abide by UN resolutions to stop its uranium enrichment, which it ensures is for peaceful purposes.
"There is no aim and goal to achieve any sort of nuclear weapons," he said, but noted that atomic weapons in the region were a problem, with Israel, India and Pakistan all in the nuclear club.
"Iran does not have nuclear weapon, and does not intend to have such," he insisted.
Khatami faced an angry reception from human rights campaigners, who say that Iranians were detained without trial and tortured during his time in power.
Under his presidency, Iranians experienced some press freedom and social liberties, but his reform plans were often blocked by conservatives.
