Supporters in Parliament Square have heard from speakers including Sadiq Khan , the mayor of London, as well as shadow cabinet members Keir Starmer, Diane Abbott and Emily Thornberry.
They will also hear from shadow chancellor John McDonnell.
“I’m proud to stand with hundreds of thousands of people in demanding that they, not wealthy, privileged and out-of-touch hard-right Tory MPs, have the final say on what is an even worse deal than Theresa May’s,” Mr McDonnell said ahead of the march.
“Our policy is clear: Let the people decide.”
The crowd cheered on Saturday afternoon as MPs voted to withhold support from the prime minister’s Brexit deal.
“Hear us,” some chanted outside parliament, while others shouted: “People’s Vote!”
A number of celebrities have also joined the march, including the actors Patrick Stewart and Stephen McGann.
