Members of Lancaster For Europe joined more than 100,000 people in London to demand a “people’s vote” on the final Brexit deal.
The march in the capital which converged in Parliament Square on Saturday June 23 was the country’s biggest ever pro-European march.
Jon Moore from Lancaster For Europe said: “It was an amazing day out, but the huge numbers show the strength of feeling.
“The People’s Vote campaign is taking off across the country.
“In Lancaster For Europe, we have seen our membership increase in recent weeks as it has become clear the government is intent on a bad Brexit deal that will destroy jobs, harm our NHS and wreck the future of young people.
“Whether you were a Leaver or a Remainer two years ago, no one now really thinks Brexit is going well.
“We didn’t know about the £40 billion divorce bill back then or that promises on extra money for the NHS would be broken.
“And it certainly looks like our political leaders in Westminster are making a mess of it.
“Here in Lancaster we will be out campaigning all summer to make sure the people get their democratic right to have their voice heard on Brexit.”
As the pro-EU protest reached its rally point in Parliament Square, another was heading in the same direction.
The UK Unity and Freedom march said it was focusing on “freedom from the EU, freedom from terror, freedom of speech, freedom from Sharia law, and unity of all people, irrespective of race or creed”.
The UK voted to leave the European Union on June 23 2016. It is scheduled to depart on March 29, 2019.
The UK and EU have provisionally agreed on the three “divorce” issues of how much the UK owes the EU, what happens to the Northern Ireland border and what happens to UK citizens living elsewhere in the EU and EU citizens living in the UK.
Talks are now focusing on the detail of those issues and on future relations - after agreement was reached on a 21-month “transition” period to smooth the way to post-Brexit relations.
