Several hundred anti-Brexit protesters are marching on Parliament today with their dogs to demand a second referendum.

Pet owners have taken to the streets with their pooches for the 'Wooferendum' demonstration to try to pile more pressure on Theresa May over the crunch talks.

They are ramping up their efforts to try to force the Government to put whatever Brexit deal it thrashes out with the EU to a public vote.

It comes as Nicola Sturgeon today said the SNP will back a second Brexit referendum vote if it comes to Parliament.

Dog owners, including Tony Blair's former spin chief Alistair Campbell, marched through central London for today's rally.

Ministers revealed last month that pets-owners who want to take their dogs and cats abroad to the EU with them face having to make plans months in advance if there is a no deal Brexit.

Protesters out today carried banners declaring it is time to 'bark out' against Brexit and that it is time to get 'paw-liticial'.

While organisers of the march set up stations along the route so that canines could relieve themselves on pictures of the leading Brexiteer Nigel Farage.

Eurosceptics back last-ditch compromise on Brexit in bid to kill off Chequers Former Tory leader Iain Duncan Smith (pictured at the Tory Party conference in Birmingham last week) says Brexiteers are prepared to let EU officials be stationed at British ports after the UK's departure in order to get a Canada-style free trade deal Brexiteers have backed a last-ditch compromise plan to kill off Theresa May's Chequers plan as the clock rapidly runs down on the crunch talks. Former Tory leader Iain Duncan Smith said they are prepared to let EU officials be stationed at British ports after Brexit in order to get a Canada-style free trade deal. Brexiteers are furious at Mrs May's Chequers plan - which they say will mean the UK will have to keep swallowing EU rules and be unable to strike global free trade deals. Today Mr Duncan Smith and Jacob Rees-Mogg backed plans for the border force officials, which they say mean EU customs and single market rules can be enforced on goods heading to the bloc without the UK having to stick to them. Writing in the Sunday Telegraph, Mr Duncan Smith said allowing EU officials at UK ports - as happens now with Eurotunnel - would answer concerns about the Irish border. He wrote: 'We can... (conduct) regulatory and customs checks together in a way that respects the EU's single market, by building on systems already in place at the Channel Ports. 'The UK has long had arrangements with France under the Le Touquet Treaty where passports are checked by French officers at Dover and UK officers in Calais. 'The UK should seek to build on this by agreeing a Le Touquet-plus system with the EU.' Advertisement

But the ex Ukip leader hit out at the marchers, telling MailOnline: 'As Brexit day nears the remoaners become more desperate. their bizarre stunts leave normal people shaking their heads.'

The protesters will march through London before ending up outside Parliament where Labour MP and leading Remainer Stella Creasy will address the crowds.

Tiffany Haynes, 32, a dog walker from London, took Welsh Collie Megan with her to the march.

She said: 'I think this is a nice idea for a protest, it's a clever way of doing it because dogs make light of politics and bring people together.

'People can relate to each other more with their dogs.'

Ministers admitted last month that Britons will find it far harder to take their pets abroad to Europe if Britain crashes out of the bloc without a deal.

Under current rules Britons can get pet passports, which allows them to take their cats and dogs abroad as long as they have a rabbies vaccination and a microchip.

But if Mrs May does not get a deal then Britain will become a 'third country' and pet owners face having to register their animal three months in advance of travelling to the country.

Today's protest comes as Brexiteers have backed a last-ditch compromise plan to kill off the PM's Chequers plan as the clock rapidly runs down on the crunch talks.

Brexiteers are furious at Mrs May's Chequers plan - which they say will mean the UK will have to keep swallowing EU rules and be unable to strike global free trade deals.

And anger is mounting among Tory Brexiteers at reports that the PM is ready to offer Brussels another compromise to unblock the talks.

She is expected to suggest a backstop to avoid a hard Irish border which would the UK remains in a customs arrangement with the EU, with Northern Ireland closely aligned to the single market.

But today Mr Duncan Smith and Jacob Rees-Mogg backed plans for the border force officials, which they say mean EU customs and single market rules can be enforced on goods heading to the bloc without the UK having to stick to them.

'The UK has long had arrangements with France under the Le Touquet Treaty where passports are checked by French officers at Dover and UK officers in Calais.

'The UK should seek to build on this by agreeing a Le Touquet-plus system with the EU.

'Any customs or regulatory checks could be made at juxtaposed controls with information-sharing and cooperation between the UK and the Republic of Ireland.

'This would not simply answer concerns about keeping the Northern Ireland border open - it would also ensure the channel ports continue to provide as frictionless trade as possible.'
