The BBC made the wrong decision in axeing Jeremy Clarkson, Sir David Attenborough has suggested, saying it was "very good" to have anti-establishment voices at the corporation.

Sir David, the veteran broadcaster and former BBC Two controller, said he "regrets" that the corporation let Clarkson go.

The former Top Gear presenter left the BBC after a so-called "fracas" during the filming of the series, and has since moved to Amazon while Chris Evans took over hosting the original motoring show.
