Generally speaking, you should presume that anything you write down or record about an individual may be shown to that individual at some point in the future (see question 14 on 'subject access requests'). This includes any comments or personal opinions that you write down about interviewees. There are certain exemptions which may mean that you can delay or prevent disclosure, but they are very narrow, and very strictly interpreted, so you should always seek legal advice before relying on them.
