Tunnel protesters sing and drum their way into Stonehenge

Police and officials maintain presence at mass trespass after bypass approved

More than 100 protesters have staged a trespass at Stonehenge to raise concerns over plans for a two-mile tunnel underneath the world heritage site.

Last month the transport secretary, Grant Shapps, approved the 1.7bn project, which will include eight miles of extended dual carriageway along the A303 in Wiltshire.
