Green MP Caroline Lucas has promised to continue her fight to end fracking after being found not guilty of obstructing a public highway and a public order offence.
"We will continue to campaign to end fracking and only celebrate when our world is on the path to a clean energy future," Ms Lucas said outside court.
She was arrested outside energy company Cuadrilla's exploratory oil drilling site in Balcombe, West Sussex, in August last year.
