Since 1947 the people of Norway have provided London with a tree out of gratitude for the support Britain gave the country in World War II. This year the annual tree lighting ceremony will take place in Trafalgar Square on the 6 December.
This is the 66th year London has been presented with a Christmas tree from Oslo in Norway.
Decorated in traditional Norwegian style with hundreds of white lights, the lighting of the tree helps mark the start of the festive season in the capital.
The tree provides a focal point for the Christmas Carol singing programme which runs from 6 to 22 December and will remain in Trafalgar Square until early January 2013, when it will be taken down for recycling.
