A previously unseen photograph of the Prince of Wales with his grandson George features in a video to promote Earth Hour.
A photograph of a smiling Prince Charles cuddling his grandson Prince George has appeared for the first time in a video made by the Prince of Wales to promote climate change awareness.
The picture can be seen in the bottom left hand corner of the screen as the Prince delivers
a video message in support of Earth Hour.
Charles will become a grandfather for the second time this spring, when his daughter-in-law the Duchess of Cambridge gives birth to George's younger brother or sister.
Some of the world's most famous landmarks were plunged into darkness on Saturday evening as millions of people around the world switched off their lights for an hour to raise awareness about climate change.
Buckingham Palace, London's Tower Bridge, Old Trafford football stadium and Big Ben, were just some of the buildings taking part in the WWF's Earth Hour.
