Seven Labour frontbenchers have announced that they will take part in the Put it to the People march tomorrow to demand a fresh Brexit referendum.
They will join hundreds of thousands of people in London on Saturday to support calls for public to be given the Final Say on Brexit.
Their presence, along with that of London mayor Sadiq Khan, is likely to add to pressure on the Labour leadership to fully endorse another public vote.
Jeremy Corbyn has backed a fresh referendum on Theresa May's deal if it is approved by MPs but has suggested his priority is securing a softer version of Brexit.
He is under pressure from MPs and party members to wholeheartedly endorse calls to give the public a Final Say vote regardless of what Brexit deal, if any, is passed.
The march, which is being supported by The Independent , will also include former Conservative deputy prime minister Lord Heseltine, Scottish first minister Nicola Sturgeon and a host of celebrities.
They will be joined by Labour shadow ministers Clive Lewis, Rosena Alin Khan, Marsha de Cordova, Luke Pollard, Rachael Maskell, Steve Reed and Matt Rodda.
Hundreds of thousands of people are expected to attend, making the event one of the biggest political marches in UK history.
Speaking ahead of the protest, Mr Khan said: " Brexit is a complete and utter mess. We're now days away from falling off a cliff edge with catastrophic consequences. Enough is enough. It's time to take this out of the hands of politicians and put it back to the people.
“ I’ll be marching on Saturday with people from every part of our country – from every walk of life - to demand that the British people get the final say. No matter how you voted in the referendum, we can all agree that the path we’re being forced to follow is not in the national interest. Everyone now deserves to have their say in how we move forward as a country."
Dozens of MPs and peers from all of the main political parties will also take part, including former Conservative cabinet ministers Justine Greening and Dominic Grieve, The Independent Group's Anna Soubry and SNP Westminster leader Ian Blackford.

Announcing his attendance, Lord Heseltine said: “The Put it to the People march will give voice to the growing concern in the nation that Brexit is going horribly wrong.
“ This is a march to stop this madness. The last two years has seen a great unravelling, of the promises made during the referendum, of the prime minister's deal and of trust in politics. Now, with a deal barely no-one supports and certainly no-one loves and with time running out to free our parliament from deadlock the only way I can see to resolve this national crisis is to take this decision back to the British public."
He added: “ There is another way. A final defeat for the prime minister's deal should be the signal for MPs from across the political divide to work together to find first the political will and then the time and space to hold a People's Vote .
“ Europe stands ready to help but we need to work together to find a solution to this crisis of our democracy.
Protesters will also hear speeches from young campaigners and people from across the UK, including a 96-year-old Second World War veteran who is travelling from Devon and a man who is walking from Swansea to London to join the march.
