A man has admitted exploiting a vulnerable worker who was kept in a freezing 6ft (2m) shed for 40 years.
Peter Swailes, 56, denied conspiring to facilitate travel of another with a view to exploitation, but changed his plea at Carlisle Crown Court.
The defendant's father, also Peter Swailes, 80, was accused of the same offence but died in September 2021.
It rescued the victim, then 58, from the shed in October 2018.
The hearing heard he had been sleeping on the floor with a soiled duvet.
There was only one window which could not be fully closed and it was in complete darkness when the doors were shut.
The GLAA said the victim had been sleeping in conditions "that no human being should live in".
