Thousands of anti-Brexit campaigners have gathered in central London calling for a second referendum in what has been dubbed the biggest rally in years.
The People’s Vote March set off from Park Lane at midday and will end as activists gather in a rally in Parliament Square.
Joe Trickey, from Croydon, is celebrating his 83rd birthday at the march.
He said: “I believe very strongly in the EU as a place of peace and strength.
“Going out puts us in isolation and leaving isn’t about trade deals, it’s about our values.”
Mr Trickey is protesting alongside his daughter, who is holding a sign about his birthday, and plans to celebrate afterwards with “a glass of wine”.
Thousands of campaigners are marching through central London, with Sadiq Khan joining the young voters group holding a People’s Vote banner.
Some 100,000 people were expected to gather in London on October 20 as part of a demonstration demanding a referendum on the final Brexit deal
The London Mayor and chef Delia Smith are among those due to speak at the event.
Simon Chater is part of the Devon for Europe group, which arranged eight coaches to bring campaigners to London for the event.
The 69-year-old from South Devon said: “This is the first time in my life I’ve been political.”
He said 400 people had travelled in coaches arranged by the group, with some leaving Devon at 6am.
Marching under the “Islanders for Europe” sign, Glenn Kobanny said he had travelled from the Isle of Wight this morning to be part of the protest.
