It’s hard to think of two institutions more British than the Royal Family and Sir David Attenborough.
So perhaps it makes sense that the TV naturalist is close to several members of the Royal Family, from the Queen herself, right down to Prince George.
Sir David’s relationship with the royals can be tracked back to 1958, when he was pictured meeting Princess Anne and Prince Charles, then aged six and nine, at the BBC studios after they watched a children’s programme being filmed there.
He also developed a good relationship with the Queen as he produced her annual Christmas broadcast between 1986 and 1991.
He had by that point already been knighted, being awarded the honour at Buckingham Palace in 1985.
But in 2020, he was knighted for a second time. Sir David has also been given a personal award by the Queen, showing their special relationship.
Now Prince William is ensuring the royal friendship continues. He asked the naturalist to be on the judging panel for his new project, the Earthshot Prize.
The prize will give away £50m over the next decade, to projects which help solve some of the problems facing the world.
Sir David has even met the youngest Cambridges - giving Prince George a fossilised shark’s tooth as a present.
At 94, Sir David proves there is no age limit to a royal friendship.
