Magic Radio will be joined by Basil Brush as guest hosts, while Minions, The Powerpuff Girls, Bumblebee from Transformers will be among characters from television and film who will be parading along Regent Street, together with marching bands, dancers and toy vehicles.
A Barbie activation will also take place while other characters featuring in this year's line-up are from Scooby Doo and Wacky Races. Characters from Cbeebies and Paddington will also make a return appearance.
The event will end with a fireworks display.
