Nottinghamshire councillor Jason Zadrozny has pleaded not guilty to 24 sexual offence allegations.
He faces four serious allegations of a sexual nature when the alleged victim was 13, and four further charges relating to an assault against the boy, by getting him to perform a sexual act.
The councillor, who sits on both Ashfield District Council and Nottinghamshire County Council, also faces four charges of gross indecency, and 12 counts of sexuality activity with a child.
He appeared at Nottingham Crown Court today to enter a not guilty plea, following an initial hearing in March.
All the offences are said to have happened between 2003 and 2006.
He had previously faced nine sexual offence charges, but this has now been changed by the prosecution to allege 24 incidents.
Mr Zadrozny, of Sutton Road, Kirkby-in-Ashfield, was released on bail until his next appearance in October. A trial has been pencilled in for January 2017.
Zadrozny is standing as an independent candidate in the Police and Crime Commissioner elections on May 5, against five other candidates.
