Peter Prendiville, from Craigdarragh Park in Holywood, County Down, used to teach maths.
The 60-year-old also stood as a Belfast City Council candidate for the Social Democratic Labour Party.
Prendiville has been ordered to sign the S.
Appearing before Downpatrick Crown Court in County Down, he admitted making pornographic images of children on dates between February 2007 and July 2010.
While many of the titles of the images are too graphic to repeat, one charge relates to Prendiville possessing 1,921 pornographic underage images along with a video of violent child rape lasting just over 15 minutes.
His lawyer told the court there were “ongoing discussions” between the prosecution and defence regarding the “charges and categorisation” of the images involved in some of the charges.
No facts of the case were opened during Tuesday’s hearing, but the judge said that given the accused’s guilty pleas to the charges, he must sign the police sex offenders register as a bail condition.
Prendiville was then released on continuing bail.
Prendiville represented the Social Democratic Labour Party in the east Belfast constituency during the 1983 Westminster election.
