Spying on Iran: How MI6 infiltrated the IAEA

Leaked confidential files indicate the International Atomic Energy Agency was infiltrated by a veteran British spy who has claimed credit for sanctions on Iran. The documents lend weight to the Islamic Republic’s accusation that the nuclear watchdog secretly colluded with its enemies.

Part 3 - MI6’s man on Iran takes credit for “maximum pressure” strategy

While leading the Foreign Office’s Iran Department from 2006 – 2008, Langman oversaw a team seeking to “develop understanding” of the Iranian government’s “nuclear program.”

It’s unclear exactly what that “understanding” entailed. But the document makes clear that Langman then “generated confidence” in that assessment among “European, US and Middle Eastern agencies” in order to “delay programme [sic] and pressurise Iran to negotiate.” The reference to “Middle Eastern agencies” strongly implied MI6 cooperation with Israel’s Mossad intelligence service.

In April 2006, Tehran announced it had successfully enriched uranium for the first time, although officials denied any intention to do so for military purposes. This development may have triggered Langman’s intervention.

The Islamic Republic has rejected any suggestion it harbors ambitions to possess nuclear weapons. Its denials were corroborated by a November 2007 US National Intelligence Estimate expressing “high confidence that in fall 2003, Tehran halted” any and all research into nuclear weapons. This assessment remained unchanged for several years, and was reportedly shared by the Mossad, despite Benjamin Netanyhau’s constant declarations that Iran was on the brink of developing a nuclear weapon.
