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 4 December.
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 Monday 8 to Tuesday 23 December and will remain in Trafalgar Square until 6 January 2013, Twelfth Night, when it will be taken down for recycling.
