Human rights advocate Bianca Jagger, the former wife of Rolling Stone Mick Jagger, has visited a controversial fracking site in support of residents.

The former actress and model, 68, visited the Cuadrilla site in Balcombe on Sunday to join protesters who have occupied the area since Thursday.

Protesters were delighted with her support and Ms Jagger, who is founder and chair of the Bianca Jagger Human Rights Foundation, took to Twitter to voice her support.

She said: ""Very moved by the brave people of #Sussex who are trying to stop #Cuadrilla from #fracking their beautiful #balcombe countryside.

Pls JOIN (sic).”

Six more arrests were made yesterday after Friday’s protest stopped oil firm Cuadrilla moving their lorries in to begin digging the 3,000ft (914m) well and 2,500ft (762m) horizontal bore at the site.

A spokesman for Cuadrilla said: “We are working hard to get up to speed. We experienced slight delays but we’re looking to get back on schedule as soon as possible.

“There were some issues on Friday when protestors meant we were unable to bring our trucks in, which did delay us somewhat.”
