Kennett

During the military procession, a Torch for Peace, organised by the Commonwealth War Graves Commission, will be passed between a young person and Alan Kennett, aged 100, who served during World War Two.

But among the 5,500 sites identified by Right to Roam as having no basic legal right of direct public access are the East Kennett long barrow in Wiltshire, a neolithic burial mound first protected as a scheduled monument in 1924, and the Holne Chase Iron Age hill fort in woodland on the edge of Dartmoor in Devon.

However, the owners of the East Kennett site told the BBC that they were happy for people to visit with permission, as safety was an issue when horse training took place nearby.

Justice Geoffrey Kennett found the global ban was not a reasonable requirement to place on the platform.

“It would be a clear case of a national law purporting to apply to persons or matters over which, according to the comity of nations, the jurisdiction properly belongs to some other sovereign or state,” Kennett added.
