An army of council workers has swept the streets of London to clear up the mess left behind by the tens of thousands who flocked to the banks of the Thames to see in the New Year.
Crowds lined banks and bridges along the river, braving intermittent spells of rain ahead of a midnight display featuring around 12,000 fireworks which produced 50,000 projectiles.
The mayor's fireworks display was ticketed for the second year and was sold out.
The celebrations went ahead as planned, despite a similar display in Brussels being cancelled due to safety concerns and German authorities warning of a "serious imminent threat" at stations in Munich.
After the London display passed off successfully, a huge clean-up operation got underway in the early hours of this morning to remove the tonnes of litter left behind.
Council workers swept the streets removing the glass bottles, plastic bags, cans, and drinks cartons left behind by revellers.
Last year almost 85 tonnes - or 15 double-decker buses worth - of rubbish was deposited on the capital's steets following the celebrations.
The Metropolitan Police said there were a total of 48 arrests overnight, including four for drug possession, three for carrying offensive or bladed weapons and five for assaults on police officers.
Six people were also detained for public order offences, 11 for assault and one for sexual assault, the Met said.
The force confirmed New Year's Eve was one of two events - along with Notting Hill Carnival - in which there was no holiday entitlement, meaning all available staff were called upon.
The Met said it had worked closely with the mayor's office, British Transport Police (BTP), Westminster City Council and others to ensure the event ran smoothly.
Met spokeswoman Superintendent Jo Edwards said the extra officers were for reassurance and the event was "successful".
She said: "Our officers worked alongside stewards to support their operation and help people to get in and out of the event area safely and efficiently.
"Although the celebrations have drawn to a close, officers continue to work through the night to facilitate the clean up operation and bring the area back to normality in time for the New Year's Day parade."
