‘You can’t block the M5’: police prepare for mass protests at Cornwall G7 summit

Local force says it has identified more than 30 groups planning some kind of action during event

Activists are expected to disrupt next month's G7 summit in Cornwall by blocking main roads into the county, trying to obstruct convoys carrying world leaders and perhaps even targeting a cruise ship that will be anchored off the coast as extra accommodation for police officers.

Devon and Cornwall police are preparing for thousands of protesters to head to the far south-west of Britain for the 11-13 June event, which is centred on the seaside village of Carbis Bay and the towns of St Ives and Falmouth.
