A BBC Antiques Roadshow expert became emotional as he refused to value an item linked to the slave trade on Sunday's (31 March) episode.
Ronnie Archer-Morgan assessed a disc of ivory a guest said she bought 36 years ago for £3; it was engraved with the name of a person and a ship, which he said signified it belonged to an indigenous trader from Nigeria.
The visibly emotional antiquarian explained his great-grandmother was a returned slave from Nova Scotia who came back to Sierra Leone.
"I do not want to put a price on something that signifies such an awful business," he said.
