A rare parchment copy of the US Declaration of Independence has been found by a team of researchers in the southern English city of Chichester.
The West Sussex County Council says it is "the only other contemporary manuscript copy of the Declaration of Independence on parchment apart from the signed copy at the National Archives in Washington DC."
The copy of the United States' founding document was discovered among the papers of an aristocrat who supported the American rebels against the British.
DNA tests reveal the parchment is made of sheepskin and its high iron content indicates that nails may have been used to hang it.
