But former UKIP leader Nigel Farage has hit back saying the Remainer march did not represent the majority. Prime Minister Theresa May hinted on Friday that she might not bring her twice-defeated EU divorce deal back to parliament next week, leaving her Brexit strategy in meltdown. Pro-EU protesters will gather for a "Put it to the people march" at Marble Arch on the edge of Hyde Park around midday.



They will then march past Number 10 Downing Street before finishing outside Parliament.



James McGrory, the director of the People's Vote campaign and one of the organisers of the march, claimed the campaign for a second Brexit referendum is now the biggest mass movement in Britain, dwarfing the membership of the main political parties.



He said: "People from all walks of life see can what they were once offered bears no relation to what is being delivered and they are angry about it because it feels like a bad deal is being rammed down their throats.” As many as a million people could flood the streets of London after estimates for a similar rally in October were as high as 700,000.

Two hundred coaches from around Britain were booked to take people to London for the march.



One coach left the Scottish Highlands on Friday evening, and another left from Cornwall on England's western tip early on Saturday morning.



A petition to cancel Brexit altogether has also gained more than four million signatures in just three days after Mrs May told the public "I am on your side" over Brexit, urging lawmakers to get behind her deal.



In the June 23, 2016 referendum, 17.4 million voters, 52 percent, backed Brexit while 16.1 million, 48 percent, backed staying in the bloc.

But ever since, opponents of Brexit have been exploring ways to hold another referendum.



Mrs May has repeatedly ruled out holding another Brexit referendum, saying it would deepen divisions and undermine support for democracy, and yesterday ruled out revoking Article 50.



Brexiteers believe a second referendum would trigger a major constitutional crisis.



Some opinion polls have shown a slight shift in favour of remaining in the European Union, but there has yet to be a decisive change in attitudes.



Labour Deputy Leader Tom Watson will address the rally

However leader Jeremy Corbyn will not

Many voters in Britain say they have become increasingly bored by Brexit and May said on Wednesday that they want this stage of the Brexit process to be "over and done with."



Labour deputy leader Tom Watson is due to speak at a rally at the end of the march - but the party’s leader Jeremy Corbyn, who has been accused of sidestepping the debate over a second referendum, will not. Mr Watson is expected to tell marchers that the only way to resolve the Brexit impasse is "for people themselves to sign it off". Elsewhere in the country, former UKIP leader Mr Farage joined the rival March to Leave in Nottinghamshire, and took a swipe at Remainers, saying he believed if there was another referendum, Leave would win by an even bigger margin.
