More than 100 children and their parents staged a demonstration at Sefton Park School to protest against plans for its expansion.

Wearing high-visibility vests, the youngsters marched with their mums and dads half a mile along Ashley Down Road to land next to the City of Bristol College.

The 20-minute walk was organised to highlight the dangers pupils could face under the plans.

The land has been earmarked as new playing fields, and parents are furious that the only current way for their children to reach the site would be along the busy main road.

Hannah Jenkins, 38, of Maycliffe Park, marched with her son Charlie, 7, who is in Year 3.

Mrs Jenkins said: "I just don't think it is viable, and wouldn't give permission for my child to take that walk. All you need is for a child to trip and fall into the road. It is just not safe."

And her son, Charlie, added: "I am quite cross about the walk. If I had to walk all this way it would be really annoying and I wouldn't like it. I would be worried and scared about the cars."

One parent, wheelchair user Liz Crow, was concerned that the journey along the narrow pavements would be difficult for disabled children and could alienate them from their friends.

Others pointed out that by the time children had walked to the site, got changed and later walked back, there would be little time for sport and games.

Stephen Williams, Liberal Democrat MP for Bristol West, who joined the march, said: "It would be ridiculous to put children's safety at risk, and they would spend more time walking to and from the site than they would on the field."

Plans to expand Sefton Park School from 420 places to 630 are currently under consultation by Bristol City Council.
