Children join the festivities at London's Notting Hill Carnival family day
Thousands of partygoers have flocked to Notting Hill Carnival in a surge of colour and music.
More than a million visitors are expected to attend the celebrations in west London on Sunday, the day dedicated to children and families.
Children in fancy dress and face paint claimed the best view of the parade by sitting on parents' shoulders, and some even joined the dancers following the parade floats.
Annuar Aziz, a businessman from Malaysia, stumbled upon the event by accident with his wife and four young children while on holiday.
He said: "It's excellent. We are loving the free spirit of everyone and we have all been dancing.
"We didn't even know it was happening," Mr Aziz, 41 explained.
"We just arrived to London after visiting the Fringe Festival in Edinburgh.
"We heard the music from where we are staying in Bayswater and just followed the sound."
At least 60 bands will perform and 38 sound systems will be in place over the two-day event, which continues over the bank holiday. It will end with its Grand Finale day on Monday.
There is a heavy police presence in place as the Met has introduced advanced security measures, including a facial recognition system.
The Carnival, celebrating Caribbean culture in London, was first held in the 1960s and now attracts visitors from all over the world.
Police said they had arrested 47 people at the event by 6.30pm for a variety of alleged offences.
These included two alleged sexual offences, 3 7 drugs offences, 13 counts of possession of offensive weapons and alleged theft and public disorder.
London Ambulance said staff on duty had treated 179 patients and taken 27 to hospital.
The service tweeted a picture of paramedics setting up extra beds along the street as its treatment centre got busier into the evening.
