Notting Hill Carnival: A'sha's ready!

Notting Hill Carnival is one of the world's biggest street parties.

It happens on the last bank holiday of the summer and over its two-day stretch nearly one million people take part.

There are processions and brightly coloured costumes with lots of Soca music - a type of music which originated in the Caribbean.
