The 680th Lord Mayor of London, David Lewis, waves as his carriage winds its way through the streets of the Square Mile for the Lord Mayor's Show.
The yearly procession is three miles long, travelling from Mansion House to the Royal Courts of Justice on The Strand.
At the end of the parade the Lord Mayor takes an oath of allegiance to the Queen before the Lord Chief Justice.
An acrobat performs during the show, which dates back almost 800 years, showcasing the city's culture and history.
The Lord Mayor of London is head of the City of London and fulfils a mostly social and ceremonial role, unlike Mayor of London Ken Livingstone.
About 6,000 people and 70 floats took part in the parade, including troops who have recently served in Afghanistan.
The event, which was preceded by a RAF flypast, ends with a fireworks display from a barge in the Thames moored between Blackfriars and Waterloo bridges.
