Brexiteer Britons are toasting in a new era for the UK outside the European Union with parties, pub crawls and rallies across the country.
The celebrations got into full swing well before 11pm, when Britain finally divorced from the bloc after three and half years of wrangling.
From the flagship Leavers party in London's Parliament Square, to the social clubs of Warrington in the North West, merry revellers waved Union Jacks and wished each other a 'happy Brexit day'.
Champagne corks were also popped in the other home nations, with gatherings in Glasgow and Belfast continuing long into the night.
People also decorated their homes for Brexit-themed dinner parties and erected British flags along their streets.

This evening, the Union Jack flag will fly on every flag pole in Parliament Square ahead of a 'once-in-a-lifetime' party as Britain officially leaves the bloc at 11pm.
And across the country clocks will ring out to mark the country's departure, as thousands across the United Kingdom prepare celebrate the 'bright new future' that independence from the European Union will bring.
Not everyone is celebrating however, with vigils planned by pro-EU supporters and flares let off in London as disgruntled Remainers vent their frustration at Britain's eventual departure from the bloc.
Remainers are scrawling 'I love EU' on 50p coins with permanent marker and releasing them back into circulation, in a last-ditch attempt to anger Brexit voters.
Karen Hoyles, from Devon, posted pictures of her defaced coins online, calling for others to follow suit.

In an appeal to her Twitter followers, she hoped for people to 'get their creative juices flowing' and release '10million' 50ps with the phrase.
Another apparent Remain supporter, Nigel Callaghan, claimed to have found two defaced 50ps, a pound and a two pound coin in his 'change'.
Mr Callaghan appeared to sarcastically say it might have been 'treason' if the Queen's face had been drawn on while also outlining how people could write on coins with a Sharpie.
The protest comes as Royal Mint announced its release of a special edition gold Brexit 50p coin, which can be purchased for £945 by those wishing to commemorate the occasion.
But for many, today is a turning point after political stagnation and delay. On what will be a special moment, one thrilled Briton claims he'll finally crack open a bottle of Scotch he's had saved for 25 years after waiting for just the 'right time', while pubs are offering up free British grub to celebrate local produce.
Party organisers claim the country is finally 'moving forward' and this evening's celebrations will be about 'bringing people together' as they celebrate a 'piece of British History' with raffles, tribute acts and discos.
Those organising events up and down the country and keen to make everyone feel included in this evening's entertainment - designed to mark Britain's departure from the European Union at exactly 11pm.
Ray Singleton, 72, is organising a Brexit celebration event at his men's club in Stapleford, Nottingham. He told MailOnline that he had decided to organise the event around two weeks ago and it is about 'bringing people together'.
'The reason we are celebrating is because it's a piece of British History. It is not a celebration to say we won, you lost, its about bringing people together and to go forward together.
'The overwhelming sentiment of our Members, whichever side of the divide they are on, are just pleased its done, the political infighting has finished and we are moving forward. We hope our little event will go some way to achieve those aims.'
Explaining what entertainment will be on offer, he said: 'We will be having a Disco/Karaoke, plus a special guest who's act specialises in Vera Lynn tributes, and she will be serenading us with Land of Hope & Glory plus a few other old classics at around 11pm.
'We are serving free food and we have reduced our bar prices to £2 a pint and spirits to £1 a shot to help with the celebrations.'
The celebrations have caused quite a 'media frenzy', Mr Singleton explains. Yesterday we did interviews for BBC Radio 4, which will be broadcast today. Radio Nottingham will be doing a Live link from the Club at 10.30pm.
'East Midlands News are sending a camera crew to the Club today to do interviews and to film the celebrations. Additionally, Broxtowe's newly elected MP, Darren Henry has accepted our invitation to join in the fun, so a very busy day for all concerned.'
Bill Bailey, the landlord of the Cricketers in Westbourne, West Sussex, - who is also organising a Brexit Party - said celebrations had been a long time coming however.
'This has been so long waiting for this to come to a close. I think which ever way you voted it's been a lot of money spent on the whole thing which could have been used elsewhere. So what ever the outcome you wanted let's just embrace it and move forward for Britain.
He added: 'We are have our party with live music free Yorkshire puddings with beef in just for a beer soaker as one does we here are all looking forward to a new Britain.'

A controversial anti-Brexit group hijacked the White Cliffs of Dover before dawn today and beamed a pro-EU film in English, French and German on to its famous chalk face to display a 32,000 sq ft 'message to Europe' that Britain will rejoin the bloc 'before long'.
Protest group Led by Donkeys filmed two Second World War veterans called Sid Daw, aged 95, and 97-year-old Brigadier Stephen Goodall, who both describe their grief as the UK leaves the EU at 11pm tonight.
Mr Daw, who fought as a sniper in the Second World War, says of the EU: 'We want to be together and we will be together before long, I'm sure'
The guerrilla video, apparently projected from a boat below the cliffs, ends with the stars on the EU flag slowly disappearing - with just one star remaining, the line reads: 'This is our star. Look after it for us.'
95-year-old Sid Daw, who was a sniper for the Allies, introduces the video and says: 'This is a message from the White Cliffs of Dover, from Britain'. Mr Daw, from Cardiff, fought in France, Holland, Belgium and Germany during the conflict.
He says: 'First of all, I'm Welsh, and I'm British, and I'm European and I'm a human being. I feel very, very sad about it all because we don't know which way things are going.'
Appealing to fellow Europeans on the Continent, he said: 'Look from your side to this side, see these white cliffs, and we're looking across at you feeling we want to be together and we will be together before long, I'm sure.'
