Exclusive: Sources within Whitehall have confirmed that GCHQ intercepted communications revealing new details of Iran's nuclear programme, just hours after the UN Secretary-General confirmed that inspectors had been granted access to a previously undisclosed site near Isfahan. The intercepts, obtained by this newspaper, suggest that Tehran is deliberately concealing enrichment activities at a military facility not declared to the International Atomic Energy Agency. The intelligence, shared with allies, indicates that Iranian scientists have been developing advanced centrifuge designs under the guise of civilian research.
This revelation comes as a blow to the diplomatic efforts to revive the 2015 nuclear deal, which the Biden administration has been pursuing. A senior intelligence source stated: "The Iranians have been playing a dangerous game.
They talk of transparency but their actions betray a clear intent to deceive." The UN chief's confirmation of inspections had been hailed as a breakthrough, but these intercepted documents paint a different picture: one of systematic duplicity. The Iranian mission to the UN did not respond to requests for comment.
The findings will likely escalate tensions between Tehran and Western capitals, with the UK's Foreign Office calling for an emergency session of the IAEA Board of Governors. This is a story that will run, and run.
