A Millennium project to re-enact the journey of a bluestone from west Wales to Stonehenge has hit a new hitch which would not have befallen Stone Age man.

Organisers of the £100,000 lottery-funded project have been unable to find an insurer to cover the stone's sea journey.

Lee Mullins, spokesman for the Bluestone Project said: “The project is currently unable to gain the specialist maritime insurance cover necessary for the sea stage of the journey.”

This is the latest in series of problems faced by the ill-fated project. Insurers got cold feet when the bluestone nearly slipped from a platform between two leather-covered canoes.

The overland journey was also delayed when organisers ran out of volunteers to help transport the stone.
