Tens of thousands of Britons opposed to the country’s withdrawal from the European Union marched through the streets of London on Saturday to demand a vote on the final Brexit deal.

The protesters waved the blue and gold flag of the European Union under sunny skies to mark the second anniversary of the referendum that was decided in favor of Brexit.

Britain is set leave the European Union in March 2019. But the government plans to give Parliament a vote on the final deal — if one is reached with the European Union — later this year.

Caroline Lucas, a parliament member and co-leader of the Green Party, said at the demonstration that she rejected the government’s “vision of a mean-minded little Britain” and citizens should have the right to vote on any deal.
