Crowds have flocked to The Notting Hill Carnival to enjoy the colourful costumes, Caribbean music and food and a parade of giant floats. Over one million people are expected to attend the event over the next two days which is the biggest street festival in Europe. London Mayor Boris Johnson says the festival highlights what the Caribbean community does for London.

Organisers say this year marks the first milestone in the build-up to the event's 50th anniversary in 2016. However some people believe the first carnival took place in 1964, while others say a street parade with music and dance took place the following year.

A number of business owners and residents have boarded up their properties on the carnival route in a bid to avoid damage. Six thousand police officers are attending the festival to ensure it remains a safe, vibrant and enjoyable event. Officers say they will quickly identify and remove anyone prohibited from the event.
