No. You are protected by parliamentary privilege. However, if your evidence comments adversely on another person, the committee will send the comment to the other person so they can reply.
'Adverse comment' is usually considered to be comments which, if they were not protected by parliamentary privilege, might justify suing for defamation: for example, allegations of professional incompetence, negligence, corruption or deception. Merely criticising another person's views is not adverse comment.
The committee may choose to take evidence that contains adverse comment confidentially.
If you repeat your comments outside the committee hearing, you are not protected by parliamentary privilege.
