Transporting a 60ft Christmas tree 700 miles from Norway to London is no easy task, so how was it done?
The Great Britain boat which is competing in this year's round-the-world Clipper Race is on display in Trafalgar Square.
A giant blue cockerel by German artist Katharina Fritsch has been unveiled on the Fourth Plinth in Trafalgar Square.
Trafalgar Square's Christmas tree has been delicately moved into position, before the lights are switched on later this week. Cranes were used to lift the 60ft tree earlier today. This 30 second timelapse video shows how it was lifted.
Work has begun to install the 50 year old, 60 foot tall, Norwegian Christmas tree in Trafalgar Square.
Every year since 1946 the Norwegians have gifted a magnificent spruce pine as a thank you to Britain for our support during the Second World War. The lights on the tree will be switched on this Thursday.
Martin Stew was in Norway last month as the tree was cut down before it began a 700 mile journey.
The Trafalgar Square Christmas Tree will arrive in the capital this morning after its journey from Norway. The spruce is donated by the City of Oslo to the people of London each year as a token of gratitude for Britain's support during the Second World War.

A robotic arm in London is replicating the exact work of an artist as he draws an image of a face 900 miles away in Vienna. Video of Alex Kiessling is being projected onto a big screen in central London. Alongside him, a yellow robotic arm, copying his every move perfectly.
Alex Kiessling used an infra-red sensor to trace the movements of his pen and send the signal via satellite to the industrial robots in Trafalgar Square that reproduced on canvas the lines he was drawing. Kiessling said it took more than six months to perfect the technique and the software.
The three versions of Kiessling's "Hybrid head" were made, one full face with two half heads on either side. They will be joined together and exhibited in Vienna and London.
