The Jeremy Kyle Show producers treated guests like criminal suspects, the MP leading an inquiry into reality TV has claimed.
The House of Commons culture select committee heard from two of the show's former guests on Wednesday.
Dwayne Davison, who first appeared in 2014, told MPs he was locked in a small room and had his phone taken off him.
"I think someone in police custody would have more rights and better treatment," Damian Collins MP said.
The committee is investigating whether enough support is offered during and after filming on reality TV. The inquiry was set up after the death of a man who had taken a lie detector test on The Jeremy Kyle Show, and the suicides of two former Love Island contestants.
