Museum piece

Although it's been in England for more than a hundred years, questions are being raised in Italy over the rightful home of an ancient mosaic. Housed in London's Victoria and Albert Museum, the piece is one of many treasures that legally made its way to Britain. But politicians in the town of Orvieto, where the mosaic is from, say it's morally theirs -- and they want it back. The BBC's Daniela Relph reports from Orvieto.
