Lord Mayor's show: The 'early morning rehearsal'
The new Lord Mayor of London, Fiona Woolf, takes office on Friday - only the second woman to do so.
As the head the City of London Corporation, her duties include promoting British trade and the services of the Square Mile.
On Saturday she will take part in the Lord Mayor's Show - but BBC News got a sneak preview at the "early morning rehearsal" in which the golden state coach was taken out while most of London was still asleep.
