Norwegian trumpeter Tine Thing Helselth is preparing to greet the Christmas tree on London's Trafalgar Square with a special musical performance at the ceremonial lighting this evening.

Audiences can expect performances of Christmas carols from the trumpeter, who is set to play In the Bleak Midwinter , and choral versions of The First Nowell , The Holly and the Ivy , and We Wish You a Merry Christmas from the choir of St-Martin-in-the-Fields. St Clement Dane's primary school will perform their poem Friendship inspired by the gift of the tree.

Since 1947, the people of Norway have given London a Christmas to thank Britain for her support during World War II. The tree will remain on Trafalgar Square until January 5.
