Notting Hill Carnival, Europe's biggest street party which showcases Caribbean culture, has descended on the streets of west London. More than 750,000 people are expected during the two-day event, which begins with a children's parade later.
The 44th carnival's theme, ‘Welcoming the World’, is in keeping with the Olympic handover ceremony in Beijing. Police have installed metal detectors on the three-mile route to try to stop the carrying of guns and knives.
