It is that time of year again when crowds will descend on the streets of London for the annual Notting Hill Carnival, which is now in its 48th year.
More than one million people are expected to attend the event over the next two days.
There will be familiar scenes of dancers in brightly-coloured outfits dancing to calypso beats on lines of colourful floats during parades that have taken months of planning.
The carnival also gives revellers a chance to get a taste of the Caribbean with many stalls selling Jamaican delicacies such as ackee and saltfish, not to mention fried dumplings and rice and peas.
Thousands of police officers will be deployed to ensure the day stays fun. Officers have already arrested 27 suspected troublemakers ahead of the carnival.
Scotland Yard has confirmed 5,000 officers will be on duty on Sunday and 7,000 officers on Monday.
Commander Bob Broadhurst, in charge of the policing operation, said: "Well over one million people attend the Notting Hill Carnival every year. Given these huge numbers, crime is low.
"What we want is for those million people to enjoy the event without worrying about the crime and violence that has been caused by the small minority in the past."
A 20-year-old man was stabbed during last year's festival.
