The Christmas tree lights in Trafalgar Square are on, and the festive season is upon us.

Princess Astrid of Norway did the honours, lighting the 69th tree to be sent to Britain from Norway.

Oslo has gifted the people of Britain a tree – usually a spruce – every year since 1947, and it will stand prominently in Trafalgar Square until January 6.

Isn’t it pretty?

The spruce and its bright lights will definitely make the cold nights a little bit more bearable for those out in central London.
