Today we go back to 1986, when an Israeli nuclear technician Mordechai Vanunu revealed his country's secret nuclear weapons programme to a British newspaper. Mike Lanchin has been speaking to the journalist who helped publish the story.
We were tense, we were exhausted and most people there had never done a story as big as this.
And the gist of the story, what was it?
That, not only had Israel secretly produced between 100 and 200 nuclear weapons, but it was the sixth largest nuclear power and yet it had done so secretly without anybody knowing.
Peter Hounam is the investigative journalist with the scoop. But he's worried because the man who's told him about Israel's most treasured secret has now disappeared.
He had been rigged up, as uh, he promised to do. And I was getting more and more worried. We were due to publish this story that weekend, but we had no Vanunu.
Vanunu was Mordechai Vanunu, a Moroccan Jew who'd worked as a technician on Israel's secret nuclear programme. Peter Hounam had first met him in August of that year, in a hotel in Sydney Australia. Initially, both men were suspicious of each other.
