The Trafalgar Square Christmas tree has been felled in Norway, ready to begin its journey to London.

The felling ceremony took place yesterday in Rausjø, near Oslo, and the tree's lights will be lit by Oslo mayor, Per Ditlev-Simonsen, on December 4.

It will be the 56th tree sent to Britain by Oslo in a tradition begun after World War II, to thank the UK for its help to Norway and Norwegians fleeing the conflict.

According to the UK embassy in Oslo, the tree was found after weeks of 'scouring the woods'.

"The 100 year old tree is 21 metres tall and bristles with contentment, with fine green and fresh branches," the embassy said in a statement.

Four other trees, felled after the UK's tree, will be sent to other European cities and Washington.
