James McGrory, director of the People's Vote campaign, which organized the march, said before the protest that the government should hold another referendum on EU membership.
"This new deal bears no resemblance to what was promised to the population (in 2016) and therefore it is only fair that the public deserve another chance to give their opinion," he said.

"I'm angry that we are not listening. Almost all research shows that now people want to stay in the EU. We feel we have no voice," protester Hannah Barton said. "This is a national disaster waiting to happen and it will destroy the economy," he adds.
