Slow-driving convoy caused long delays to those heading to Devon and Cornwall on the first day of the school holidays

Protesters campaigning against high fuel prices have disrupted holiday getaways to the south-west of England by driving in convoy slowly up and down a motorway before blockading a petrol station.

The convoy drove at 30mph on three lanes of the M5 north and south in Somerset and the Bristol area on Friday morning as tens of thousands of people headed to Devon and Cornwall to begin summer breaks.
