London has been presented with a large Norwegian tree each winter for over 60 years as a token of friendship and gratitude for Britain’s assistance during World War II.   For 2013, the Christmas tree will be lit at 6pm on Thursday 5th December, at a ceremony featuring the Lord Mayor of Westminster, the Mayor of Oslo, St Martin in the Fields choir and the Salvation Army.
