Seventy sandbags of "sacred soil" from the First World War battlefields of Flanders will be carried through the capital today on their way to a memorial garden which will mark next year's 100th anniversary of the start of the war.
The bags arrived in London yesterday and will be taken by gun carriage from HMS Belfast to Wellington Barracks, where the Flanders Field Memorial Garden is being created.
On the way the carriage will pass national landmarks such as St Paul's Cathedral and Buckingham Palace.
The bags were delivered by the Belgian Navy frigate Louise-Marie, which sailed through Tower Bridge, opened fully in recognition of the event.
