Boris Johnson news: PM faces fresh court action over Brexit ‘lies’, amid more jeers on UK tour as Irish leaders unite against him

Welcome to The Independent's politics liveblog, where we will be bringing you all the latest updates throughout the day.

Here is our front page today, where our main story looks at Boris Johnson's clash with Irish premier Leo Varadkar over his Brexit demands.

Boris Johnson is in Northern Ireland today, where he is holding talks with the main political parties this morning.

He arrived at Stormont House at around 8.15am, and was greeted outside by Northern Ireland secretary Julian Smith. 

After a private lunch with Boris Johnson last night, Arlene Foster, the leader of the Democratic Unionist Party (DUP), said the confidence and supply agreement continues - and will be reviewed at the end of this parliamentary session.

But speaking to BBC Breakfast, the DUP leader said conversations last night with the new PM centred on Brexit and restoring the Northern Ireland executive at Stormont that collapsed in January 2017.

Ms Foster also lashed out a the European Union, telling Brussels and Dublin to "dial back on the rhetoric" - before, of course, accusing them of being "very belligerent" and attempting to break up the United Kingdom.

She told the BBC: "Like the prime minister, I want to leave the EU with a deal, but it has to be a deal that respects the constitutional and economic integrity of the UK.

"Unfortunately the previous withdrawal agreement did not do that because of the backstop. The backstop that separated Northern Ireland out from the rest of the United Kingdom."

"We talked about the fact that Dublin and indeed Brussels needed to dial back on the rhetoric and be a willing partner to find a deal, not just for the UK but for the Republic of Ireland and the whole of Europe.

"No deal is on the table because of the fact we have a very belligerent European Union, who instead of focusing on a deal that was good for all of us, wanted to break up the United Kingdom.

"Something of course that no British prime minister should be a part of."

The Conservative Party will be "annihilated" at a general election if it fails to deliver Brexit by October 31, Nigel Farage has said.

Mr Farage praised Boris Johnson's performance since being installed in Downing Street, but warned that voters should remain sceptical about Mr Johnson's ability to deliver a no-deal Brexit.

Mr Johnson did not intend to depart the EU by Halloween but was seeking to improve Britain's negotiating position over the Withdrawal Agreement, Mr Farage wrote in The Daily Telegraph.

He added: "It must not be forgotten that Johnson voted for it at the third time of asking. If passing this is now his ambition for Brexit, my party will vigorously oppose him."

The Brexit Party is preparing to run candidates in a general election in Labour-held constituencies in the north of England, the Midlands and Wales.

Mr Farage said the Tories could never win the seats, which had mainly voted Leave in the 2016 referendum.

But the Brexit Party leader said he will not form an alliance with the Tories while Dominic Cummings is Mr Johnson's special adviser on leaving the bloc.

Mr Farage has previously cast doubt on Mr Cummings's Brexit convictions.

He said: "Lack of trust in the Conservatives is now a problem; many of us will only believe in a clean-break Brexit when we see it.

"Britain's best chance of achieving independence now comes from the Brexit Party.

"If the UK does not leave on October 31, the Conservatives will be annihilated in any subsequent general election."

New analysis of Google search trends suggests a vanishingly low level of public awareness of the possibility of a no-deal Brexit at the time of the EU referendum in 2016.

Foreign secretary Dominic Raab said earlier this week that campaigners for a Leave vote had made clear during the referendum that the UK would strive to reach a Brexit deal with the remaining EU, but would leave without one if necessary.

But records of terms entered in the internet search engine show no evidence whatsoever of Britons inquiring about a Brexit deal or a no-deal outcome at the time.

Sinn Fein president Mary Lou McDonald has branded Brexit a "piece of astonishing political and economic self-harm".

She told BBC Radio 4's Today programme: "I think it's very important that the British system sets out very clearly for all of us what it and they would understand to be the point of threshold, the trigger point at which a border poll or a referendum would be called ... Well, I think some of the thresholds have been met."

On no-deal, she added: "In the event of a hard Brexit and a crash Brexit, I don't know for the life of me how anybody could sustain an argument that things remain the same...

"I don't know how Britain could crash this part of Ireland out of the EU with all of the attendant harm and damage economically and politically and, with a straight face, suggest to any of us who live on this island that we should not be given the democratic opportunity as per the Good Friday Agreement to decide our future.

"I think that would be quite scandalous."

Niall Collins, foreign affairs spokesman for Ireland's opposition party Fianna Fail, said the "hardening" of Mr Johnson's rhetoric "concerns us".

He told Today: "The backstop is necessary for a number of reasons as we know, it's necessary to protect the all Ireland economy, it's necessary to protect the Good Friday Agreement to avoid a hard border on the island of Ireland and all the consequences that would flow and will flow if we have a border on the island of Ireland, including the potential damage to our peace process and potential return to violence."

Mr Collins warned that "there can't be any pre-conditions to talks between Boris Johnson and the EU leaders" over Brexit.

He said: "We have negotiated with our European colleagues a Withdrawal Agreement with the British Government and that is the agreement within which we have to work.

"And any amount of, I suppose, debate or seeking to unravel that just simply isn't the case, there's too much at stake."

Boris Johnson has insisted that a private dinner with the DUP has not undermined his impartiality in efforts to restore powersharing.

The PM dined with Arlene Foster and other senior figures in Belfast on Tuesday amid ongoing negotiations aimed at renewing the Conservatives' confidence and supply deal with the DUP.

Critics have claimed the government is unable to act as an impartial mediator in talks to restore the crisis-hit institutions due to the controversial Westminster deal with the DUP.

Mr Johnson denied a conflict of interest as he arrived at Stormont House on Wednesday.

"It's all there in the Good Friday Agreement, we believe in complete impartiality and that's what we are going to observe," he said.

"But the crucial thing is to get this Stormont government up and running again."

One of the big stories today is comments from top No 10 aide Dominic Cummings, who told a conference that Conservative party MPs “don’t care about the NHS” and are apathetic about poor people.

Boris Johnson’s right-hand man in Downing Street expressed the damning views at a conference in 2017, claiming the public were “correct” to believe Tory politicians didn’t care about the people who relied most upon the health service.

Mr Cummings' appointment has sent shockwaves through Westminster - as the former Vote Leave chief has been outspoken in his criticism of MPs and civil servants/
