More than 20,000 singers, musicians and soldiers have worked for months to create a backdrop to this event, a procession for the Queen's Golden Jubilee leading from
Buckingham Palace to St Paul's.
The Queen leaves the Palace at 10.40, and travels in the Gold State Coach past a 5,000-strong choir who perform Handel's Zadok the Priest.
David Dimbleby fronts the coverage, with Philippa Forrester, Sophie Raworth and Wesley Kerr.
Producers Daniel Brittain-Catlin and Catherine Stirk
