Viewers couldn't get enough of the Queen and David Attenborough talking about trees

Two national treasures came together to speak about trees, and the nation loved every second of it.

In The Queen’s Green Planet, a one-off documentary about the Queen's plans to plant a global network of forests, David Attenborough and Her Majesty took a stroll through the gardens at Buckingham Palace.

• How the Queen is putting politicians to shame with her Commonwealth Canopy project
• The Queen’s Green Planet director describes what it was like working with two “kindred spirits”
• “She is very unsolemn” – David Attenborough reflects on filming with the Queen

Since the ITV special aired on Monday night, viewers have been marvelling at how enjoyable it was to simply watch two 91-year-olds getting excited about trees, and many called for a whole series of Attenborough and the Queen having a chinwag.

The Queen's Green Planet also featured contributions from Princes William and Harry, as well as Angelina Jolie, who called Her Majesty a "really lovely lady”.
