A postman from Cornwall has denied 27 charges of sexually abusing children and having images of child pornography.
Michael Williams, who is also a part-time taxi driver, pleaded not guilty to sexually grooming children and inciting sexual activity with a child.
At Truro Crown Court, he also denied charges of voyeurism as well as possessing or making indecent images.
Williams, who is 28 and from Tresooth Lane in Penryn, is due to go on trial in July.
Mr Williams pleaded not guilty to all 27 charges one-by-one as they were read out to him in court.
Mr Williams, who also worked as secretary for a local football club, is due to appear in court again in May for a case hearing and is scheduled to stand trial on 19 July.
