Hundreds of protesters from across the UK have taken part in a protest march over test oil drilling in West Sussex.

The Solidarity Sunday demonstration near Balcombe is the latest stage of a sustained anti-fracking protest. Energy firm Cuadrilla, which is conducting the test drilling, has refused to rule out the use of the controversial technique.

Local residents and campaigners from further afield explained why the issue is so important to them.
