Notting Hill Carnival opens with children's day

Europe's biggest street festival, the Notting Hill Carnival, has opened with thousands of revellers watching a parade of giant floats through London's streets.

Up to one million people are expected over two days for a feast of Caribbean culture, food, music and dance, now in its 49th year.

Hundreds of youngsters took part in the children's day of the carnival, which traditionally starts the event.
