Nigel Farage's Brexit Party has dented both the Tories and Labour after deciding to contest the general election in seats across the country, a new poll suggests.

The eurosceptic upstart surged four per cent in a new YouGov survey of voting intentions.

Boris Johnson's Tories were down one per cent at 38 per cent, while Labour had lost two per cent in falling to just 25 per cent.

It comes after Mr Farage took aim at the two parties and revealed 600 candidates to stand across mainland Britain.

The Brexit Party is now on 11 per cent, just five per cent behind the Liberal Democrats, who were unchanged on 16 per cent.

Despite the surge in support however, his party may save Remainers such as Ed Miliband, Yvette Cooper and Tom Watson at the election, a study shows.

Polling data by Chris Hanretty of Royal Holloway University of London suggests the Brexit Party could split the Leave vote in more than 30 Tory target seats, potentially robbing Boris Johnson of a Commons majority.

Mr Farage came out fighting today, taking a swing at Boris Johnson as he hit the campaign trail in a boxing ring.

Lib Dem leader Jo Swinson sets out her Remainer plan to 'stop Brexit and build a brighter future' using a £50billion 'Remain bonus' Liberal Democrat leader Jo Swinson set out her stall for Government today, vowing to 'stop Brexit and build a brighter future' for Britain. She launched the Remainer party's election campaign this morning with a dig at Boris Johnson and Jeremy Corbyn, painting them both as Brexiteers. The Liberal Democrats have vowed to put a £50billion 'Remain bonus' into public services if they win the General Election. At the launch event in central London this morning she said: 'Any type of Brexit will damage our economy, will cost jobs and starve our public services of the resources that they need. 'So we know that that Remain bonus will be £50 billion that we can spend on our public services, investing in our schools and in the welfare system to help the poorest in our society. 'So every vote for the Liberal Democrats is a vote to stop Brexit and invest that £50billion in our public services.' Advertisement

The Brexit Party leader accused the Prime Minister of chasing a 'Remainer's Brexit' - a jab at the Brexit deal he agreed with Brussels.

Mr Farage was in Bolsover at the start of a tour of Labour-voting Leave seats he believes his party can take from Jeremy Corbyn's party.

The Derbyshire seat of veteran firebrand Dennis Skinner voted 70 per cent to Leave in 2016.

Addressing the crowd at Bolsover Boxing Club Mr Farage said Mr Johnson's deal would 'effectively break up the United Kingdom'.

'Ninty five per cent of what Boris Johnson is trying to sell as his great new deal is actually the bad old treaty,' he said, adding: 'Without the Brexit Party we will not get a genuine Brexit, and I am going to make sure this cause is best prepared for elections across the country.'

Mr Corbyn hit out at Mr Farage's plan to target Labour Leavers this morning. Making a speech of his own in Harlow, Essex, he said: 'Nigel Farage is a one trick pony from a very wealthy organisation. Nigel Farage is going to various parts of the country saying all kinds of things.

‘He is not offering to defend the NHS in those places - indeed he has form in supporting privatisation of our NHS.

‘He is not offering housing, social justice, reducing inequality in this country or meeting the needs of people who use food banks just to survive because of poverty in Britain.

‘He doesn’t actually offer anything to any of those communities and so our message, our manifesto, our policy is about invest in in all parts of this country.’

Jeremy Corbyn accuses Boris Johnson of 'Thatcherism on steroids' and promises to 'get Brexit sorted in six months' - but refuses to rule out revoking Article 50 to form coalition with Lib Dems as he rants about US food laced with 'rat hair'

Jeremy Corbyn has accused Boris Johnson of trying to 'hijack' the UK's departure from the European Union to unleash 'Thatcherism on steroids' as he claimed Labour would resolve Brexit in six months.

Setting out Labour's Brexit policy in a speech in the swing seat of Harlow in Essex this morning, Mr Corbyn claimed Mr Johnson wanted to 'sell out' the NHS in a post-Brexit trade deal with the US and 'strip away' the rights of workers - accusations fiercely denied by the Tories.

He tried to seize control of Mr Johnson's Brexit message of 'get Brexit done' as he said a Labour government would 'get Brexit sorted' by the middle of next year.

However, he failed to rule out the possibility of revoking Article 50 as the potential price of forming a coalition with the Liberal Democrats if there is a hung Parliament.

Labour is campaigning in the run up to the election on December 12 on a platform of staying neutral on Brexit.

If Mr Corbyn becomes PM he would then negotiate a new divorce deal with the EU before facilitating a second referendum.

That referendum would pitch Mr Corbyn's Brexit deal against Remain and Labour would decide which way to campaign in the weeks leading up to the national ballot.

Mr Corbyn also used the speech to sound the alarm about what he believes are the risks of doing a trade deal with the US as he claimed it would likely lead to lower food standards which could mean maggots and rat hairs in produce.

The key lines from Jeremy Corbyn's Brexit speech On the NHS: 'Boris Johnson’s Conservatives want to hijack Brexit to sell out the NHS and sell out working people by stripping away their rights.' On post-Brexit food standards: 'They’ll slash food standards to match the US, where what are called “acceptable levels” of rat hairs in paprika, and maggots in orange juice are allowed and they’ll put chlorinated chicken on our supermarket shelves.' On Thatcherism: 'What Boris Johnson’s Conservatives want is to hijack Brexit to unleash Thatcherism on steroids.' On a second referendum: 'A Labour government will get Brexit sorted within six months by giving you, the British people, the final say.' On failing to pick a side on Brexit: 'People sometimes accuse me of trying to talk to both sides at once in the Brexit debate; to people who voted leave and remain. You know what? They’re right. Why would I only want to talk to half the country?' Advertisement

Speaking in Harlow, Mr Corbyn said: 'This threat to our NHS isn’t a mistake. It’s not happening by accident. The threat is there because Boris Johnson’s Conservatives want to hijack Brexit to sell out the NHS and sell out working people by stripping away their rights.

'Given the chance, they’ll run down our rights at work our entitlements to holidays, breaks and leave.

'Given the chance, they’ll slash food standards to US levels where “acceptable levels” of rat hairs in paprika and maggots in orange juice are allowed and they’ll put chlorinated chicken on our supermarket shelves.

'And given the chance, they’ll water down the rules on air pollution and our environment that keep us safe.'

Mr Corbyn claimed Mr Johnson wants there to be a 'race to the bottom in standards and protections' so that the UK can move to a 'deregulated American model of how to run the economy'.

He added: 'What Boris Johnson’s Conservatives want is to hijack Brexit to unleash Thatcherism on steroids on our society.

'The Thatcher government's attack on the working people of our country left scars that have never healed and communities that have never recovered.'

Mr Corbyn said the Tories 'know they can’t win support for what they’re planning to do in the name of Thatcherism so they’re trying to do it under the banner of Brexit instead'.

Mr Corbyn's references to Mrs Thatcher are likely to have been designed to shore up Labour support in Leave-voting working-class areas of the country where the former Tory PM is remembered with anger.

Leave-voting seats which are currently held by Labour are key to both main parties' hopes of winning a majority on December 12 with Mr Johnson expected to aggressively pursue them.

Mr Johnson last night challenged Mr Corbyn to set out Labour's Brexit policy in detail a letter sent to the Labour leader.

Today Mr Corbyn insisted that a second referendum on Brexit would not be a 're-run of 2016'.

Mr Corbyn said the December 12 election represented a 'once in a generation chance' to change the UK

Jeremy Corbyn claims UK food standards will drop under Tories because of 'sell out' trade deal with the US Jeremy Corbyn today claimed US food is laced with 'rat hair and maggots' as he accused Boris Johnson of plotting a 'sell out' trade deal with Donald Trump. In a dramatic escalation of his rhetoric, the Labour leader said Mr Johnson is trying to 'hijack' Brexit so he can lower standards. The veteran left-winger said the Tories are preparing to unleash 'Thatcherism on steroids', opening up the NHS to US pharmaceutical companies and stripping workers of their rights. 'Given the chance, they'll run down our rights at work, our entitlements to holidays, breaks and leave,' he said. 'Given the chance, they'll slash food standards to US levels where 'acceptable levels' of rat hairs in paprika and maggots in orange juice are allowed and they'll put chlorinated chicken on our supermarket shelves. 'And given the chance, they'll water down the rules on air pollution and our environment that keep us safe. They want a race to the bottom in standards and protections.' The jibe is a reference to the difference in approach between US and EU food standards. The Food and Drug Administration (FDA) has guidelines on 'maximum levels of natural or unavoidable defects in foods for human use that present no health hazard'. Advertisement

Mr Corbyn told activists in Harlow: 'A Labour government will get Brexit sorted within six months by giving you, the British people, the final say. And despite what some commentators want you to believe, Labour’s plan for Brexit is clear and simple.

'It’s time to take the decision out of the hands of politicians and trust the people to decide.

'It won’t be a rerun of 2016. This time the choice will be between leaving with a sensible deal or remaining in the European Union. That’s the policy. It really isn’t complicated.'

The Labour leader said the Brexit deal he secured would take 'no longer than three months' to finalise.

That Labour deal would be 'based on terms we’ve already discussed with the EU, including a new customs union, a close single market relationship and absolute guarantees of rights and protections'.

Mr Corbyn pitched Labour's policy as a win for both Leave voters and Remainers as he said: 'So if you want to leave the EU without trashing our economy or selling out our NHS, you’ll be able to vote for it. If you want to remain in the EU, you’ll be able to vote for that.

'Either way, only a Labour government will put the final decision in your hands.'

He added: 'To finally get this sorted and move forward we need the people to sign on the dotted line.'

Mr Corbyn has repeatedly been accused of trying to sit on the fence on Brexit as he has refused to back Leave or Remain.

He tried to embrace the criticism today as he said: 'People sometimes accuse me of trying to talk to both sides at once in the Brexit debate; to people who voted leave and remain.

'You know what? They’re right. Why would I only want to talk to half the country?'

The Tories believe Labour's proposed softer Brexit deal would have to include a commitment to keeping freedom of movement - something which could be poorly received in some Labour-held Leave-voting constituencies.

Mr Corbyn was asked after his speech in Harlow if freedom of movement would continue under his plans but he dodged the question.

The Conservative Party has pledged to end freedom of movement once the UK has left the EU. Mr Johnson wants to introduce an Australian-style points-based immigration system instead.

Mr Corbyn was asked after his speech if he would accept revoking Article 50 as the price of forming a coalition government with the Lib Dems if December 12 resulted in a hung Parliament.

He failed to rule out such a possibility as he said: 'All I can say is we are campaigning to win this election with a majority Labour government. We are not campaigning to form a coalition with anybody.'

The Lib Dems have said that if they win a majority at the election then they would cancel Brexit on day one of a government led by Jo Swinson.

Ms Swinson today said she is 'absolutely categorically ruling out' Liberal Democrat votes ever putting Mr Corbyn into Number 10.

The Conservatives have consistently denied the NHS would be 'on the table' in trade talks with the US.

Donald Trump also made clear the health service would not be part of any agreement in an LBC interview last week, in which he also warned that Mr Corbyn would be 'so bad' for the UK.
