A 'copy' of the Magna Carta bought by Harvard University for £20 is actually an original worth £16million, scans have showed.
More than 700 years after the iconic document was originally drafted, new analysis has found the handwriting and sizing of Harvard's $27.50 auction snap up are consistent with authentic records.
It comes as up until now there were thought to have been just six original copies that remained of the ground-breaking charter.
Drafted in 1215 by the Archbishop of Canterbury on behalf of King John, the Magna Carta was intended to make peace with rebel barons and is credited with laying the foundations of many constitutions across the world.
The first version was annulled, though it was reissued in 1300 by Edward I, promising protection of church rights, limits on taxes and access to impartial justice.
