Jeremy Hunt, the underdog in the race to be next British prime minister, said he would take the United Kingdom out of the European Union without a deal on Oct. 31 if the EU had not showed it was willing to renegotiate the Brexit deal.
“If we got to the 31st of October, and the EU have not shown the willingess to negotiate a better deal ... then my judgment is that weighing those difficult options up, the political risk of no Brexit is far worse than the economic risk of no deal,” Hunt said at a leadership hustings event in Birmingham, central England.
“I would take us out of the European Union in that situation.”
Passengers have been facing delays at Manchester Airport after an IT failure prevented many from checking-in at all three terminals.
Some travellers said they had been waiting to check-in for more than three hours, with long queues building up.
An airport spokesman said the IT issue had been resolved in the afternoon, adding: "We apologise to our passengers for the inconvenience."
The issue first arose at 11:30 BST on Saturday.
Backlog of passengers
The airport said there were no longer any queues at check-in but there were knock-on delays to some flights.
Some airlines tried to check people in manually during the IT failure and have been working through a backlog of passengers after the issue was resolved.
Jordan Elliott was one of many to complain to the airport on social media.
He tweeted a picture of the queues and said: "@manairport in total lockdown. No-one checking in due to computer failure!"
'Utter carnage'
Michael Ripley was on his way to Fuerteventura with his family for his wedding anniversary when they got caught up in the delays.
"It's utter carnage... All the IT systems were down at check in. No-one could help us," he said.
On Wednesday, the third round of voting will take place between 15:00 and 17:00 BST. The result is expected at 18:00 and the MP with the lowest number of votes will be out of the race.
During Tuesday's hour-long debate, all five men ruled out calling a general election until Brexit was resolved.
But the encounter exposed divisions in their approaches to Brexit and whether they could accept the UK leaving the EU without an agreement.
The candidates, who faced questions from members of the public on issues ranging from climate change to Islamophobia, also disagreed over whether to prioritise tax cuts or increased spending on public services after the UK leaves the EU.
Mr Johnson, the frontrunner in the contest, was taking part in his first debate of the campaign after he skipped Sunday's Channel 4 encounter.
How candidates' Brexit plans stacked up
The former foreign secretary said the British people were "fed up" with the current deadlock over Brexit and the Tories would pay a "really serious price" if this continued.
He warned of a "catastrophic loss of confidence in politics" if the latest Brexit deadline was not met. Asked if he could guarantee this, he replied that "October 31 is eminently feasible".
"If we allow 31 October to come and go as we let March come and go, I think the public would look on us with increasing mystification," Mr Johnson said.
He also suggested there was no issue with continuing free trade after Brexit - citing something called Article 24 of GATT - but as BBC Reality Check points out, that relies on the UK and EU both signing up and in the event of no deal, that will not happen.
Mr Javid, who came fifth in Tuesday's second round of voting, said a deadline was needed to "focus minds" in both the EU and the UK.
"We have to learn from our mistakes," he said. "One of the mistakes we have made is having a flexible deadline."
He suggested the route to getting a Brexit deal through Parliament was by re-presenting Theresa May's Withdrawal Agreement but without the controversial Irish backstop.
Mr Gove said an "arbitrary" deadline was counter-productive and if he was prime minister he would be prepared to delay Brexit by a matter of days to finalise a deal.
"You sometimes have extra time in football matches in order to slot home the winner."
Mr Hunt said he would back a no-deal exit as a "last resort" but if the UK was close to finalising a deal with the EU he would extend the talks to prevent the disruption a no-deal exit would cause to business.
Both Mr Hunt and Mr Javid suggested new technology could potentially solve the intractable Irish border issue, but the EU has said there is currently none in use anywhere in the world that can keep it as open after Brexit as it is now link
Mr Stewart said he would not allow a "damaging and unnecessary" no-deal exit and his rivals could not explain how they could possibly do this "against the consent of Parliament".
He suggested he was seeking the most realistic "door" out of the EU while "everyone else was staring at the wall and saying believe in Britain".
What Europe made of the debate
EU politicians across the continent were dipping in and out of the debate. The comments I've heard so far off-the-record have not been particularly complimentary.
The EU simply thinks that most of those leadership candidates are not being realistic.
EU leaders are preparing a united, determined front when it comes to the idea of renegotiating the Brexit deal, and the answer is no.
Even if, come the autumn, the EU were to be tempted to reopen some of those questions such as the Irish backstop, those conversations could never be finished by 31 October - the date by which most of those leadership candidates want to leave the EU.
That's why this evening the EU thinks the idea of a no-deal Brexit is becoming increasingly likely.
Tax plans also a dividing line
Moving beyond Brexit, the candidates clashed over their economic plans and whether to prioritise higher spending on public services or tax cuts.
There were sharp exchanges between Mr Stewart and other contenders, Michael Gove accusing him of having "no plan" for how to run the economy or public services.
"Bringing people together is not enough," he told Mr Stewart, who has emerged as the surprise contender in the race.
However, after the debate Mr Stewart admitted his performance had been lacklustre, adding he did not think the "strange" format worked for him.
Mr Gove also took aim at Mr Johnson's plans to give a tax cut to those earning more than £50,000 a year, saying the focus should be on "helping the poorest in society".
Helping middle-earners was "sensible", Mr Johnson responded.
Mr Stewart said promising tax cuts was "wrong" given the uncertainty around Brexit.
He called for a "revolution" in care for the elderly, calling current provision a "disgrace".
Mr Hunt, who was health secretary for six years, also called for increased investment, suggesting cuts to care budgets under the current government had gone "too far".
Mr Johnson reiterated that it was his "ambition" to cut taxes for higher earners, but as Chris Mason pointed out, that seemed less committal than a "promise" to do it.
Meanwhile, speaking to Newsnight after the debate, Mr Gove said he believed he had won the debate because of what he said were his "detailed answers" and "clear plan" on Brexit.
Of his rivals, he said there were "some other great people" but added: "They will all be fantastic members of my team."
Challenge over Islamophobia
Amid claims that the Conservatives have failed to tackle Islamophobia in the party, the candidates were pressed by an imam to accept that "words have consequences".
Mr Johnson said he apologised if anything he had written, during 20 to 30 years as a journalist, or had said during his political career had caused offence.
But he defended his conduct as foreign secretary in relation to the case of Nazanin Zaghari-Ratcliffe, who remains in jail in Iran on spying charges.
He suggested his claim in 2017 that the dual British-Iranian national was actually working as a journalist in the country - which the Iranian authorities cited as a reason to increase her sentence - "did not make any difference".
"If you point the finger at the UK, all you are doing is exculpating those who are truly responsible," he said.
Mr Javid challenged the other candidates to agree to an external inquiry into Islamophobia in the Tory Party - which they all appeared to do.
Referring to Donald Trump's string of attacks on London's Muslim mayor Sadiq Khan, he said politicians should be "brave enough" to call out Islamophobia wherever it came from.

Royal correspondent(wp/bbc):::
An elderly woman is in a serious condition in hospital after a road accident involving the Duke and Duchess of Cambridge's police escort.
Prince William and Kate were travelling from London to Windsor when the woman, 83, was hurt on Monday.
The accident involved a marked police motorbike in the convoy, and the police watchdog is now investigating.
Kensington Palace said the royal couple are "deeply concerned and saddened" and have been in touch with the woman.
The woman - who is called Irene, according to the palace - was taken to hospital in a critical condition following the collision on Upper Richmond Road in Richmond, south-west London at around 12:50 BST on 17 June.
She is now in a serious but stable condition in hospital.
A Kensington Palace spokesperson said: "Their Royal Highnesses have sent their very best wishes to Irene and her family and will stay in touch throughout every stage of her recovery."
The duke and duchess are understood to have sent flowers to the woman.
Investigation launched
Watchdog the Independent Office for Police Conduct (IOPC) said it is investigating the circumstances of the collision after it was referred to them by the Metropolitan Police as is "in line with procedure".
An IOPC spokesman said: "Our staff attended the scene of the incident and after careful consideration, we have launched an independent investigation.
"The investigation is in its very early stages and the officer involved is assisting our enquiries as a witness.
"Our immediate thoughts are with the injured woman and her family and those affected by the incident."
Prince William and Kate were on their way to Windsor for the St George's Chapel service commemorating the Order of the Garter.
In January, the Duke of Edinburgh, 98, was involved in a car crash while driving near the Queen's Sandringham estate.
Prince Philip flipped his Land Rover Freelander after colliding with a Kia car as he pulled out on to the A149 in Norfolk.
A teenage neo-Nazi who called for Britain’s Prince Harry a race traitor months after his marriage to U.S. actress Meghan Markle and suggested he should be shot was jailed for more than four years on Tuesday, the BBC reported.
Michal Szewczuk, 19, posted far-right online propaganda which included an image of Harry, the Duke of Sussex, with a gun to his head with the caption “See Ya Later Race Traitor”.
It was posted months after his wedding to Meghan, whose mother is African American and father is white.
Szewczuk and his co-defendant Oskar Dunn-Koczorowski, 18, both Polish nationals, pleaded guilty to encouraging terrorism and Szewczuk also admitted five counts of possessing material likely to be useful to someone planning a terrorist act.
“Dunn-Koczorowski and Szewczuk clearly see themselves as superior to the majority of society and they feel there duty is to express their beliefs, in turn teaching others,” Detective Chief Superintendent Martin Snowden, head of counter-terrorism policing in northeast England.
“The considerable amount of material they have posted on social media channels not only reflects their extremist beliefs but was intended to encourage others to carry out despicable acts.”
Szewczuk was jailed for four years and three months while Dunn-Koczorowski was sentenced to 18 months in prison.
Other posts by the men included support for Norwegian far-right mass killer Anders Breivik and backing for the neo-Nazi group, Sonnenkrieg Division.
The largest single donation to a UK university has been given to Oxford for a new institute that will study the ethics of artificial intelligence.
Stephen Schwarzman, a US private equity billionaire who has advised Republican presidents including Donald Trump, has given the university £150m.
A new building for the study of humanities will house the institute.
The UK government said it was a "globally significant" investment in Britain.
Governments 'utterly unprepared'
At a time when universities face uncertainty over research funding because of Brexit, this is a major financial coup for the University of Oxford.
Mr Schwarzman, the chief executive of the private equity firm Blackstone, is one of America's best known billionaires.
In the past, his lavish lifestyle as a Wall Street financier has attracted criticism, but more recently he has also become a major donor to education.
Mr Schwarzman told the BBC he was giving the money to Oxford because artificial intelligence was the major issue of our age.
"At the moment, most governments are utterly unprepared to deal with this, and why would they be, it's a different type of technology," he said.
"They're going to have to rely on great universities like Oxford, and others around the world who specialise in helping them think this through."
Mr Schwarzman said universities needed to help construct an ethical framework for changes that were happening rapidly.
Some economists have warned the expansion of artificial intelligence could have a significant impact on society - including the loss of jobs due to automation - in what is sometimes called the "fourth industrial revolution".
Academics have also raised concerns about the potential for malicious use in cyber warfare and the subverting of democracy.
The donation by Mr Schwarzman to Oxford follows a $350m (£279m) gift he made to the Massachusetts Institute of Technology (MIT) to establish a centre for computing and artificial intelligence.
The study of the ethics of AI at Oxford will be in a new humanities centre, bringing together subjects from languages to philosophy.
Mr Schwarzman said it was "important for people to remember what being human is".
"Why are we here? What are you values? How does technology deal and interact with that.
"We should want it to be positive and productive for society, and technology can't be allowed to just do whatever it wants because it can. "
Accepting large donations is not without risk for institutions if controversy emerges later.
Prof Louise Richardson, the vice-chancellor of the University of Oxford, said all philanthropic gifts were reviewed to make sure they fitted with its values.
"The margin of excellence requires more than we can expect from public funding, so philanthropy is going to become more important for Oxford and other universities," she said.
The new building will also create a concert hall and other public spaces.
