There has been no security breach over mail sent by the Inquiry. Here is its statement:
"The Inquiry is in contact with a wide range of witnesses, some of whom are on the island and some are not. Much of our contact with witnesses is by telephone or electronic, but sometimes it is necessary to send documentation through the post, particularly to witnesses who are not on the island. The Inquiry has deliberately chosen not to draw attention to post, which is sent in plain, non branded envelopes or plastic document bags in the normal post. The Inquiry by necessity has to use the postal service on the island. The Inquiry views with concern the reports from Mr Harper that his private mail has possibly been tampered with and has been in contact with Mr Harper."
