See this gallery for photos of eggs found by Londoners who have joined in the Faberge Big Egg Hunt and then shared their pictures through iwitness24.

More than 200 giant decorated eggs have been scattered around the capital in hidden and unexpected locations.

The challenge is to find as many of them as you can before Easter, with a Diamond Jubilee rose gold egg worth £100,000 the prize up for grabs.

Once the hunt finishes the eggs, many designed by celebrities and leading artists, will be auctioned off to raise funds for the charities Elephant Family and Action for Children.

All the pictures in the gallery below have been submitted by users of our photo-sharing site iwitness24.
