The chap in question is The Director of the Spanish Secret Service, CNI, Alberto Sáiz, who resigned after several weeks of revelations and claims about him in the press, led by newspaper El Mundo.
There are some entertaining aspects to the story:
The paper printed a list of claims saying that Sáiz had made private use of the CNI facilities, including international hunting and fishing trips, and used his post to help family and friends.I wonder why some of our people, politicians and officials have not thought of those "sophisticated lie detectors". Or, perhaps, they did and they do not work any more than the less sophisticated thumb screws do.
When the revelations about him surfaced in the press he was then accused of using sophisticated lie detector equipment against his own agents in an attempt to track down the leaks to the press.
The Times has some details on the accusations.
