Notting Hill Carnival is the largest street party in Europe with more than two million people attending each year to follow the three-mile (5km) parade. Partygoers can expect an eclectic and dazzling parade showcasing the best of masquerade dancing, soca, calypso, steel bands and sound systems. This year there will be a 72-second silence for the victims of the Grenfell disaster, as well as new policing methods.
