Cox is natural successor, says Attenborough
Attenborou-gh, who has spent six decades bringing the natural world to TV audiences, paid tribute to Cox (above) at the annual Radio Times Covers Party at Claridge's in London.
He said: "If I had a torch, I would hand it to Brian."
Attenborough's career has included award-winning programmes including ' Life on Earth', 'The Living Planet' and 'The Private Life of Plants'.
Earlier in the night, Cox praised Attenborough's "inspirational" example.
