Young courtiers are needed to accompany a giant King John puppet through Hounslow at a carnival this July.

The model, made to celebrate the Magna Carta's 800th anniversary, will be paraded through Hounslow town centre during the Night of Festivals carnival on Saturday July 11 and Sunday July 12.

ArtReach, which is organising the festivities, wants to hear from groups of seven to 13-year-olds and 14 to 21-year-olds who are keen to join the procession.

They will help carry the King John seal and follow the giant puppet along the street to the accompaniment of live music.

They must be available to meet at the Treaty Centre in the High Street at 1pm, ahead of the parade, which will begin at 2pm each day and last for around 45 minutes.

Around 20 participants from each age group are needed each day.

The 20m-long Magna Carta parchment will feature a modern take on the ideas of freedom and democracy, which the original agreement helped cement in law.

During the two-day carnival, there will be processions throughout the day from 11am to 7pm on Saturday and 11am to 5pm on Sunday, featuring costumes and puppets inspired by George Orwell's Animal Farm and by the Mexican Day of the Dead celebrations.

Group leaders should call David Hill on 01628 675 800 or email david@artreach.biz. For more information about the carnival, visit www.nightoffestivals.com.
