A notorious British MI6 agent infiltrated the International Atomic Energy Agency (IAEA) on London’s behalf, according to leaked documents reviewed by The Grayzone. The agent, Nicholas Langman, is a veteran intelligence operative who claims credit for helping engineer the West’s economic war on Iran.

Langman’s identity first surfaced in journalistic accounts of his role in deflecting accusations that British intelligence played a role in the death of Princess Diana. He was later accused by Greek authorities of overseeing the abduction and torture of Pakistani migrants in Athens.

In both cases, UK authorities issued censorship orders forbidding the press from publishing his name. But Greek media, which was under no such obligation, confirmed that Langman was one of the MI6 assets withdrawn from Britain’s embassy in Athens.

The influence Langman claimed to have exerted on the IAEA adds weight to Iranian allegations that the international nuclear regulation body colluded with the West and Israel to undermine its sovereignty. The Iranian government has alleged that the IAEA supplied the identities of its top nuclear scientists to Israeli intelligence, enabling their assassinations, and provided critical intelligence to the US and Israel on the nuclear facilities they bombed during their military assault this June.
