Live from the streets of London, this year marks the 800th anniversary of this magnificent annual procession, featuring 24 marching bands, 200 horses, two reindeer, a flying pig, a motorcycle stunt team, and the latest James Bond car.

Gyles Brandreth and Sonali Shah will meet some of the procession's 7,000 participants as London celebrates the arrival of its new Lord Mayor. Commentary by Dan Snow.
