The newspaper explains it one way..."Diana told 'without any doubt' that she was being bugged by a five-strong surveillance team - Surveillance expert detected a device behind her bedroom wall
...She was so concerned about eavesdropping that she called in a four-man team to carry out a search for listening devices. (from Moran Security Support Services Ltd)...
Princess Diana's bedroom was being bugged two years after her split from Prince Charles, her inquest sensationally heard yesterday.
An electronic surveillance expert made the astonishing discovery after Diana asked him to check her Kensington Palace apartment for listening devices because she feared 'dark forces' were snooping on her.
Former soldier Grahame Harding located a suspected bug behind a wall in her bedroom, adjacent to a room which had been used by Charles." (more)
Mr. Harding explains it this way... (in the same article)
"My equipment detected an electronic signal which indicated that a possible bugging device may have been present behind a wall in her bedroom. Princess Diana was present when I found this signal.
"As you walk into her bedroom, I believe there was another room off it where His Royal Highness the Prince of Wales had a room and it was on that wall."
He said was unable to get behind the wall to examine the device. But there was "no indication" that the fabric of the wall had been altered. He said he swept the room again later that day and the signal had gone.
"I could not give an explanation to the reading. It could have been innocent electronic equipment in another room. But the noise behind the wall was very similar to a transmitter device."
