Caroline Lucas, the Green MP for Brighton Pavilion, has been giving evidence in court as she pleads not guilty to two public order offences during an anti-fracking protest.

She and four others are facing charges connected to the protests against Cuadrilla's exploratory tests for oil in Balcombe, Sussex, last summer.
