BBC stalwart and naturalist Sir David Attenborough is thought to be the only male TV personality left who didn’t sexually assault a co-worker in the 80s, it has emerged.

Producer and friend, Mike Jones, said: “He’s had a 57 year TV career and it’s all been completely grope-free, which is unheard of. I don’t even think he’s cheated on his wife, which is just mental.”

The 91-year-old, who is currently wowing TV viewers with his latest Blue Planet installment, said: “I spent most of 80s fossil hunting in Kent, so I think I missed the whole sexual touching thing.”

He added: “I did have a confusing moment with a silverback gorilla in 1989, but that doesn’t count as I think I was technically on the receiving end”.
