The wildlife documentary-maker will be honoured for his career achievements in an hour-long TV special titled Inspiring Attenborough: Sir David At 90, during which he will be interviewed by Scottish radio presenter Kirsty Young.

Attenborough will discuss his most memorable journeys and animal encounters from over the years, and he will be joined by filmmakers, zoologists, conservationists and biologists.

The TV regular, who turns 90 in May (16), is working on a new documentary about bioluminescence featuring creatures such as glow worms and fire flies.
