A teenager with Asperger's switched on the popular Christmas lights in Croxley Green yesterday.

Dave Edwards decorates his house in Lancing Way with thousands of Christmas lights every year.

The 81-year-old then donates any money raised to various charities. This year half of the proceeds will go towards Anna Kennedy Online - an autism charity.

Ryan Wiggins, 14, who has Asperger's, is a patron of the charity and this year had the opportunity to switch on the lights.

The other half of the money raised will go to London Air Ambulance Service.
