Patrick Stewart joined thousands of anti-Brexit protesters on the streets of London today which coincided with the Government defeat. The Star Trek actor was part of the Let Us Be Heard march which headed towards Parliament Square as Boris Johnson hoped to win a vote to secure a Brexit deal. The 79-year-old stood alongside actor Stephen McGann and London Mayor Sadiq Khan behind a large pink banner which read ‘together for the final say’. He praised the crowd for ‘transforming’ British politics after people took to the streets to demand a second referendum on Brexit.

London Mayor Sadiq Khan was one of the first politicians pictured at today’s event. On Friday he wrote: ‘I’ll be joining hundreds of thousands of people in London to make sure our message is heard loud and clear over the jeers and sneers in the House of Commons’ Sir Bob Geldof seen at the anti-Brexit protest today.

Today’s rally was organised by the pro-Remain group as a last-gasp effort to persuade MPs to vote against Mr Johnson’s deal and instead swing behind a fresh Brexit poll.On the historic day, the Commons sat on a Saturday for the first time since 1982 to debate Mr Johnson’s eleventh-hour Brexit agreement which he struck with the bloc on Thursday. As of Saturday morning, more than £500,000 has been donated to support the protest, and cross-party politicians are calling on people to get involved.More than 170 coaches from around Britain were due to arrive in London today taking people to the march. Claiming to be the only way to ‘save the country’, the People’s Vote campaign claims that the ‘only way to break the deadlock in Parliament, legitimise the outcome and allow us all to talk about something else, is to give the people the final say’.Thousands outside the Palace of Westminster cheered as they learned Boris Johnson had lost a key Commons vote on his Withdrawal Agreement, withholding approval of the deal until the legislation to implement it is in place. Pixie Geldof shared a snap from the march with her husband George Barnett, brandishing a foam finger which read ‘b******s to Boris’Following the Government defeat, four members of Labour’s front bench left Parliament to address the rally.Shadow foreign secretary Emily Thornberry told them: ‘We must put it back to the people.’This is a pivotal moment in our history and it shouldn’t be left to a handful of MPs.’She was joined by shadow Brexit secretary Sir Keir Starmer, who said it was ‘fantastic’ to see the demonstration. Today’s rally was organised by the pro-Remain group as a last-gasp effort to persuade MPs to vote against Mr Johnson’s dealHe added: ‘It’s an historic moment, we have defeated Johnson again. We are not going to let him whip out with his sell-out deal.’We will say no to him again and again. Whatever deal he brings must go back to the people.’MP Antoinette Sandbach, who had the Conservative whip removed, credited the crowd with ‘changing her mind’ on a second vote.She said: ‘My local party voted no confidence in me for resisting no deal.’It’s undemocratic and not what people voted for, but it’s honourable that I put my job on the line to protect tens of thousands of jobs that will be lost in the north west from no-deal Brexit.’ Anti-Brexit protesters have flooded on to the streets of London for a mammoth demonstration to coincide with Parliament’s crunch vote on Boris Johnson ‘s withdrawal deal The Metropolitan Police were braced for the large-scale demonstration and were pictured separating a heated exchange between the activists and a pro-Brexit counter-protestOn the earlier march, effigies of the Prime Minister had been held aloft by protesters at the demonstration, with some accompanied by their pets draped in EU flags.One group of protesters spotted near Downing Street were pulling a float depicting Number 10 aide Dominic Cummings using Mr Johnson as a puppet.With ‘Demonic Cummings’ splashed across its forehead, the figure on the float appears to be wearing a Nazi uniform, including an armband which reads Get Brexit Done, and has a Union Jack moustache.The float was being manned by Phil Jeanes, 67, who said he had driven the sculpture from Dusseldorf in Germany on Thursday night.Mr Jeanes is part of a group called EU Flag Mafia, and has lived in Essen for the last nine years with his German wife.He said the float had been specifically designed for the People’s Vote march by the German artist Jacques Tilly.It is the fourth model designed by the artist, who also made a sculpture of Theresa May with her nose impaling a man in a bowler hat.’He put 14 sketches together and we chose what we thought would be the best,’ Mr Jeanes, who is retired, said.’I suppose we were always intending to do a float for this march and you have to wait and see what is happening at the time.’Meanwhile, pro-Brexit activists also gathered in Westminster.Jason Hurt, 48, from Sheffield, was sporting a ‘I voted Leave’ T-shirt, and said he feels people who voted for Brexit are being ignored.’I voted Leave, I want my voice heard,’ he said.’It is always about the Remainers, never about the Leavers. There are 17.4 million of us, we never get our voices heard.’ Politicians, celebrities and even the stalwart eco-warrior known as Mr Broccoli (pictured) are set to join the thousands of Europhiles which are expected to turn out in their thousands The People’s Vote march clashed with a Brexiteer counter-protest. The Metropolitan Police were braced for the large-scale demonstration and many officers were pictured on the roads of the capital A young protester holds a homemade placard which says ‘BoJo’s bus goes nowhere’ at the march through London todayClaiming to be the only way to ‘save the country’, the People’s Vote campaign claims that the ‘only way to break the deadlock in Parliament, legitimise the outcome and allow us all to talk about something else, is to give the people the final say’. Mr Khan wrote in The Independent on Friday: ‘I’ll be joining hundreds of thousands of people in London to make sure our message is heard loud and clear over the jeers and sneers in the House of Commons.’Liberal Democrat MP Luciana Berger also told voters to ‘let the Prime Minister know what you think’.People’s Vote organisers are also asking people to sign a letter to Boris Johnson, EU leaders, MPs, and MEPs, asking them to allow ‘the chance to check whether we want to proceed with Brexit’. Anti-Brexit remain in the European Union supporters take part in a People’s Vote protest march calling for another referendum on Britain’s EU membership An effigy of a puppet Prime Minister being controlled by his hardline Brexiteer adviser Dominic Cummings was led down Whitehall this morning by activists wearing EU flag beretsHe was joined by shadow chancellor John McDonnell – a late convert to back a second referendum – who addressed the crowds outside Parliament this afternoon.In an email to supporters this morning, Shadow Brexit secretary Sir Keir Starmer said the letter ‘asks them to honour our shared democratic values, it asks them not to turn away from us now and deny us the chance for a final say.’Add your name to the letter now and send a message to the powerful.’James McGrory, director of the People’s Vote campaign said ahead of the protest that the government should heed the anger of pro-Europeans and hold another referendum on EU membership.He said: ‘This new deal bears no resemblance to what people were promised and so it is only right that the public deserve another chance to have their say.’Campaigners are confident that the number of people on the streets will rival a similar demonstration in March, when organisers said one million people took to the streets. A rally this size would be among the largest ever in Britain. Who is Mr Broccoli?
