VIDEO: 'Million' marchers calling for another Brexit vote take over London's streets

Marchers calling for a second “people’s vote” on Brexit took over London on Saturday.

Organizers of the “Put it to the People” demonstration claim that a million people took to the streets for the pro-European Union rally.

Pictures taken from the ground and air show the protesters dominating the famous streets of Britain’s capital city.

The organizers – from a group called “People’s Vote” – wish there to be a second referendum on the country’s relationship with the European Union.

One of the options they want to see on the ballot is for the UK to remain in the political and trading bloc, overriding the 2016 vote in which a majority of people voted to leave.

It comes after Prime Minister Theresa May agreed to delay the official Brexit date until April 12 (it was originally March 29).
