A former IT contractor for Britain's domestic intelligence service MI5 has been found not guilty by reason of insanity after sharing classified information with a foreign power.

Juan Joseph, who worked as a contractor for MI5, was charged with providing intelligence to an unnamed foreign state. The case proceeded through the British court system, where Joseph's mental state at the time of the alleged offenses became a central issue.

A jury ultimately determined that Joseph was not criminally responsible for his actions due to insanity. The verdict means that while Joseph engaged in the conduct alleged by prosecutors, he cannot be held criminally liable due to his mental condition at the time.

The case highlights ongoing security concerns about contractor access to sensitive government information. MI5, formally known as the Security Service, is responsible for protecting British national security against threats including espionage and terrorism.

Details about which foreign state received the information and the specific nature of the intelligence shared have not been disclosed publicly. The insanity verdict typically results in psychiatric treatment rather than imprisonment.
