Both Remain and Leave supporters rejoiced outside Parliament last night after MPs rejected Theresa May's Brexit deal by a majority of 230 - the biggest government defeat in history.
Protestors from both sides of the debate had been waiting on College Green and Parliament Square for the outcome of the vote since yesterday morning - although many had dispersed by the time the result was announced.
The majority of those present wanted to see Mrs May's deal voted down. A group of 'gilet jaune' protesters chanted 'Bye bye EU, bye bye' to the tune of Auld Lang Syne, as pro EU demonstrators sang 'You can stick your Brexit up your a***'.
The exchange was peaceful although police and security staff were present.
However, there were dramatic scenes earlier as a far right protester and bodyguard of Tommy Robinson was arrested.
Daniel Thomas was among protesters at a 'Yellow Vest' demonstration this weekend attended by James Goddard, who was arrested over 'Nazi' slurs aimed at Tory MP Anna Soubry last week.

The pound swung sharply last night as business leaders warned that Theresa May’s Brexit defeat has sparked a national emergency that could cripple the economy.
Sterling fell to under $1.27 in the moments after the vote, before rallying to $1.286. Against the euro, sterling fell towards €1.11 before bouncing back towards €1.13.
The bounceback came as traders bet Brexit could now be delayed and weakened – or even overturned.
Meanwhile, business leaders voiced concerns over the continuing uncertainty. Most senior City figures backed Mrs May’s deal because it ruled out the risk of no deal, which they fear could create chaos at Britain’s borders and risk a recession.
Stephen Martin, of the Institute of Directors lobby group, said: ‘As things stand, we will leave on March 29, with or without a withdrawal agreement, and yet MPs are behaving as though they have all the time in the world – how are businesses meant to prepare in this fog of confusion?’
One group of Remain protesters kept up a steady racket with a bell and a bass drum they dubbed The Liberty Bell with the words Save Our Sovereignty above it.
Brexiteer David Hurlibut, 62, from Ipswich, said: 'It's not being true to the referendum. We may as well stay in the EU.'
Remainer John Wilkins, 64, from Crediton in Devon, also wanted to see the deal blocked.
'The Government hasn't managed to find a solution to the Irish border and no one is happy with the agreement,' he said.
Remainer Tony Singh, 53, said: 'No one will support a trade deal that's detrimental to the interest of the UK.'
In nearby Parliament Square a platform and two screens were set up by those campaigning for a people's vote.
A float with a sculpture of Theresa May, Boris Johnson, Michael Gove and David Davis with the words 'Brexit is a monstrosity' circled the area.
The demonstrations ahead of the vote were calm, although a small number of 'gilets jaunes' protesters verbally abused police, calling them 'EU Police' and 'EU fascists'.
Earlier yesterday, former UKIP leader Nigel Farage posed with pro-Brexit campaigners on Parliament Square as the number of protestors from both sides continued to swell.
He claimed Mrs May had never really wanted to leave the EU.
'This should be a day of celebration for Brexiteers but unfortunately the Prime Minister never wanted us to become an independent country, her deal costs us a fortune, ties us into EU rules indefinitely and is a total shocker,' he told the Daily Star Online prior to the outcome of the
