Daniel and David Doran deny forced labour charges
A father and son have both denied forcing a man to work at their farm.
Daniel Doran, 67, and David Doran, 42, were arrested following a police raid at Cariad Farm in Peterstone, near Newport, last year.
It came after a man, missing since 2000, was found living at the same site six months beforehand.
Appearing at Cardiff Crown Court, Doran senior and junior both denied a charge of requiring a man to perform forced or compulsory labour over three years.
The charges relate to the period between 6 April 2010 and 1 March 2013.
Proceedings were adjourned until 17 February, when a case management hearing will take place.
Both men have been released on bail.
