People in Cambridge are being asked to draft a new UK constitution.
It's to mark the 800th anniversary of the Magna Carta. The event is part of a 10-week internet project to give people a direct say on how the country should be run. It takes place at Cambridge University later today.
Human rights lawyer and IPA Director Professor Conor Gearty says the lack of a formal Constitution in the UK is the basis for the crowd sourcing project.
