The Conservative leader got: "Secretly, do you really regret calling this election, now the polls have moved against you?"
Labour's national elections co-ordinator Andrew Gwynne defended Mr Corbyn's refusal to order a first nuclear strike, insisting the deterrent would still work if countries knew the United Kingdom had the weapon and would use it in retaliation. But the Liberal Democrats claimed the Labour leader could not be trusted on Brexit and attacked the Prime Minister's performance.
"I know from speaking to people around here that many who have previously voted Labour are thinking hard this time because, they tell me, they have more confidence in Theresa May as Prime Minister than they would have in Jeremy Corbyn", said the letter.
"People are saying Jeremy is a strong leader, and he is - he's got integrity and he's got principles and that is certainly coming across", she said. "Any circumstances where anyone is prepared to use nuclear weapon is disastrous for the whole planet", Mr Corbyn said. "We have a very big challenge ahead of us and I believe I can play a part in that, as all of my colleagues can".
"I could have stayed on doing that job for another couple of years and not called an election".
"And you've backtracked on your social care policy". He said he wanted an education system which offered opportunities.
After saying he thinks the "idea of anyone ever using a nuclear weapon anywhere in the world is utterly appalling and terrible", he ruled out authorising its "first use".
'It's not going to happen quickly, it's not going to happen easily, but we have to have that wish'.
He added: "I didn't support the IRA".
Mr Johnson told the Press Association: "I thought it was really spine-chilling to hear Jeremy Corbyn announce that all Labour's support for our nuclear deterrent, all Labour's support for our Armed Forces was completely meaningless because when it came to the business of defending this country he wouldn't do it".
The Labour leader attacked Mrs May for failing to sign a joint letter with leaders of Germany, France and Italy condemning President Donald Trump's decision to pull the USA out of the Paris Accord on climate change.
Mr Corbyn said: 'Of course not, that is why I made the point ... about the need for president Obama's agreement with Iran to be upheld, it's quite important actually, and also to promote disarmament in Korea'.
In awkward scenes, Mrs May listened as a partially sighted voter who had waited 18 months for counselling became emotional as she recounted a bad experience with the Work Capability Assessment.
"Whether talking about her cruel and muddled dementia tax, her underfunding of schools, her cap on public sector pay and her scandalous under-funding of mental health provision, she looked rattled".
When we went to the room to see if we could talk to him, an admin person didn't want to let us in.
"Even with all those young people who say they are going to vote and may not, Mrs May should still win a majority so I wouldn't sell your pounds yet", Page said. I think it is a serious and realistic document that addresses the issues that many people in this country face and we've been fearless enough to put it out there with all the policies that are in it'.
