Peter Benenson:
By 1966, Amnesty International faced an internal crisis and Benenson alleged[citation needed] that the organisation he founded was being infiltrated by British intelligence.
The advisory position of president of the International Executive was then created for him.
In 1966, he began to make allegations of improper conduct against other members of the executive.[citation needed]
An inquiry was set up which reported at Elsinore in Denmark in 1967. The allegations were rejected and Benenson resigned from AI.
