The images, handed to and published by the British newspaper The Sunday Times in 1986, led experts to conclude at the time that Israel had the sixth largest stockpile of nuclear weapons in the world.

Although Vanunu, now 50 years old, has recently been released from prison, the Israeli authorities insist he still possesses state secrets and must not leave the country or speak to foreigners.

In the interview, the whistleblower describes the circumstances surrounding his arrest and responds to the charges made against him that led to his sentence for spying.

Of his imprisonment, Vanunu says: "To move from being a free man, walking in the streets of London, and to find yourself in a cell is a huge fall, like you are falling from a very high building to the ground. You lose everything...but the most worst is a special case, my case, not to be as a prisoner as other prisoners, and free to talk or use the phone. They put a lot of restrictions from the beginning...they put a light, 24 hours for two years, the light in my cell. I could not sleep well."

Made by an independent production company Magnetic North, the interview also reveals many of the hidden facts about the incident and the whistleblower.
