Matt Gedge is an accredited City of London and City of Westminster tour guide, who heads up Fun London Tours.
We caught up with him on a day when he was taking a group to see the Changing the Guard. We wanted to know how he got into being a tour guide, and why London still is the best city for this kind of thing.
Matt's tours include Changing the Guard, Royal London, The Square Mile, Riverside Walk and Secret London. Even if you're a dye-in-the-wool Londoner, you'll learn lots of new trivia.
