It will soon be time for Trafalgar Square to spruce up for Christmas, with the arrival of a gift from Norway.
A spruce tree is donated from the forests of Oslo in a tradition dating back to 1947, in honour of Britain's support for Norway during the Second World War.
A mature tree around 20 metres tall is decorated in traditional Norwegian style, with vertical strings of lights – energy-efficient bulbs are now used.
The tree-lighting ceremony will take place on Thursday 6 December. Carols will be sung in the square in the evenings from Tuesday 11 to Sunday 23 December. These are free events open to everyone; many of the choirs collect donations for charity.
The timing of the ceremony and a full programme of participating choirs will be announced nearer the date.
