Protesters are set to march through central London in what has been billed as the biggest public protest against the Brexit situation to date.

More than 100,000 activists are expected to march on the capital's streets on Saturday, October 20 and demand a People's Vote on the final Brexit deal.

The rally, which will start on Park Lane and end in Parliament Square, has been backed by a raft of celebrities, including chef Delia Smith and Dragon's Den star Deborah Meaden.

London Mayor Sadiq Khan has also given his backing as calls for another vote on the final deal with the European Union and a second referendum grow.

Twice as many coaches have been booked for this march as they were for the march against Brexit earlier, at which 100,000 people attended.

When and where is the march taking place?

Protesters will begin assembling from midday on Saturday (October 20) on Park Lane in central London. The meeting point is just north of the Hilton Hotel.

They will then march to Parliament Square where speakers will deliver addresses in support of a People’s Vote from 2pm onwards.

What is the route of the march?

The march will begin by travelling down Park Lane along the eastern edge of Hyde Park. Protesters will then turn left and walk along Piccadilly and onto Trafalgar Square via St James Street and Pall Mall.

Finally, the march will proceed down Whitehall, past Downing Street, and end in Parliament Square.

Who is organising it?

The People’s Vote is a grassroots campaign with support from across the political spectrum. It has more than a million social media followers and is growing every day.

Who is speaking at the march?

Delia Smith and Deborah Meaden will be leading the march, but there will also be cross-party support including from Sadiq Khan.

Other supporters include Labour MP Chuka Umunna, Tory MPs Sarah Wollaston and Anna Soubry, Lib Dem leader Sir Vince Cable and Green Party MP Caroline Lucas.

Celebrities backing the People's Vote cause include Lena Headey, Bob Geldof, Michael Morpurgo, Tim Minchin and Dominc West.

Jamie Carragher, Patrick Stewart and Armando Iannucci have also helped to sponsor coaches for the event.

What is a People's Vote?

The so-called People's Vote is the idea of another vote on the final Brexit deal, which would likely take the form of another referendum.

Many believe the UK is heading for a no deal or bad deal Brexit - which they say is not what the country voted for in June 2016.

They want the people to be able to vote on the Government's final Brexit deal before it is set in stone.
