Britain's royal family have released pictures of Prince William, wife Kate and their three children joining the naturalist David Attenborough in the gardens of Kensington Palace.
The photographs were taken earlier this week after the 94-year-old broadcaster joined Prince William, Queen Elizabeth's grandson and second-in-line to the throne, to watch an outdoor screening of Attenborough's upcoming film.
The film, David Attenborough: A Life On Our Planet, sets out his "witness statement" on the destruction of the environment and ideas on how humans can still put it right.
Prince William, who has followed his father Prince Charles in pursuing environmental causes, has previously interviewed Attenborough, and the Queen presented him with an award for raising awareness of the danger of plastic pollution last year.
The photographs showed William and Kate standing in the garden, surrounded by their three children Prince George, Princess Charlotte and Prince Louis, while Attenborough stood at a slight distance, sharing a joke with the family.

The Duke and Duchess of Cambridge are delighted to share new photographs of their family with @DavidAttenborough. The photographs were taken earlier this week in the gardens of Kensington Palace, after The Duke and Sir David attended an outdoor screening of Sir David’s upcoming feature film 🎞️ ‘David Attenborough: A Life On Our Planet’. With a shared passion for protecting the natural world, they continue to support one another in their missions to tackle some of the biggest environmental challenges our planet faces. This includes working together on The @EarthshotPrize 🌍 the most prestigious global environment prize in history – further details of which will be shared in the coming weeks. When they met, Sir David gave Prince George a tooth from a giant shark 🦷 the scientific name of which is carcharocles megalodon (‘big tooth’). Sir David found the tooth on a family holiday to Malta in the late 1960s, embedded in the island’s soft yellow limestone which was laid down during the Miocene period some 23 million years ago. Carcharocles is believed to have grown to 15 metres in length, which is about twice the length of the Great White, the largest shark alive today.
