Staggering aerial footage shows the huge scale of the Put it to the People march as it was estimated that one million people attended Saturday's rally.

Video footage shows huge crowds of anti-Brexit demonstrators making their way from Hyde Park Corner towards Parliament in central London.

Mariella Frostrup and Richard Bacon, who hosted a rally in Parliament Square, claimed that an initial count showed that the amount of people taking part topped one million.

Independent Group MP Chuka Umunna also tweeted that an estimated one million attended the march.

Large EU flags were being flown by people throughout the length of the crowd, while marching bands, whistles, cheers and chants of "people's vote" provided constant backdrop of noise.

Demonstrators wore blue and yellow berets and flew large EU flags above the crowd as the march slowly made its way to Parliament Square.

Placards carried among the crowd called on the Government to "Revoke Article 50". Others read: "We're marching to demand a People's vote" and: "We love EU".

The Union flag, the Scottish saltire and flags of other European nations were also flown above marchers.

The size of the crowd saw people spill over into the capital's side streets as demonstrators walked from Hyde Park down to Piccadilly.

Sadiq Khan tweeted a video of the countdown launching the march, with the London mayor holding up a banner at the front of demonstrators.

He wrote: "And we're off!

"Here in London, thousands of people from across our city and country have come together with @peoplesvote-uk to send a clear message: Enough is enough - it's time to give the British public the final say on Brexit."
