Pupils from Haverstock School toured the capital in an open-top bus on Friday to celebrate their role in decorating a giant egg for the world’s biggest Easter egg hunt.

Nine girls from the school in Haverstock Hill painted a one-metre egg for the Big Egg Hunt, which aims to raise �2million for two charities, The Elephant Family and Action for Children.

Their egg is one of 200 and the Haverstock pupils were the only schoolchildren invited to take part.

They toured central London to promote the hunt which runs until Easter Sunday. Afterwards the eggs will be auctioned.

Participants in the egg hunt could win a Faberge egg worth �100,000.

Gareth Pyper, 33, art teacher at Haverstock School, said: “It’s a great experience for the kids.”
