Rishi Sunak and Sir Keir Starmer took turns answering questions from Sky News and a live audience, with a snap poll suggesting the Labour leader performed better on the night.
But what did we learn from their responses about the key issues facing the country?
Here’s a look at the key points from Sky News leaders’ event in Grimsby.
Latest updates on the general election
NHS waiting lists
With the NHS England waiting list up to about 7.5 million cases, there was some angry shouting from the audience when Mr Sunak brought up the industrial action taken up by staff in the NHS.
“We’ve not made as much progress on cutting waiting lists as I would have liked,” he said.
“That was something that I was keen to do, and it has proved more difficult for a number of reasons, obviously recovering from a pandemic is not easy.”
He faced groans and boos when he said: “I think everyone knows the impact the industrial action has had, that’s why we haven’t made as much [progress].”

Sir Keir said the government could not afford to meet junior doctors’ pay-rise demands but said Labour would “get the room and settle this dispute”.
Tory tax burden
Mr Sunak repeated his promise of “tax cuts for people at every stage for people at every stage of their life”.
Facing questions about the tax burden potentially being higher than it is now under a future Conservative government, Mr Sunak said: “What our manifesto announced is the tax cuts for people at every stage of their life – for people in work, for people that are setting up small businesses, that are self-employed, for those young people who want to buy their first home, for pensioners and for families.”

D-Day fallout
“It hasn’t been an easy 18 months in general,” Mr Sunak admitted, when asked about what has gone so wrong for his party.
“I’m going to keep fighting hard until last day of this election,” he said.

But Mr Sunak’s decision to leave D-Day commemorations early sparked widespread backlash against the prime minister.
“I was incredibly sad to have caused people hurt and upset,” he said, adding he hopes people can forgive him.
National service
When an audience member asked why a young person today would believe the Tories have their best interests at heart, Mr Sunak said he is “incredibly excited” for his daughters to do national service.
“I think it will be transformative for our country,” he added.

Tough questions for Starmer on tax
Addressing his tax plans, Sir Keir insisted “working people shouldn’t pay more tax” and repeated “no tax rises for working people”.
This includes income tax, VAT and National Insurance, but rises in fuel duty, for example, would impact working people, Rigby pointed out.
That has not been explicitly ruled out.

To help balance the scales, increasing capital gains tax could raise £14bn a year, Rigby said, but Sir Keir revealed “that is not in our manifesto”.
He said he’d be happy to pay more tax himself, despite being in the top 3% for amount of tax paid – after earning £128,000 and paying £44,000 in income tax last year.
“Yes, of course,” he said, reminding the audience his father was a toolmaker – with the often-repeated line causing some laughter in the audience – and his family “couldn’t make ends meet”.

VAT on private schools
Challenged on his plans for a VAT tax on private school education, Sir Keir told an audience member the party is removing a tax break – rather than adding a new tax.
“The position at the moment is there’s a tax break, so you pay VAT on other services, but you don’t pay for private schools,” he said.
“Now I understand why that’s been in place, but it’s a tax break that we are removing. It’s not an introduction of a new tax.”
Two-child benefit cap
Sir Keir confirmed there is no plan in his party’s manifesto to cut a two-child benefit cap, admitting it was a “difficult” decision.
“I can’t do something – I know the benefits of it and we will have a strategy for it – but I think people are fed up of politicians who before the election say we’ll do everything,” he said.

Small boat crossings and immigration
On small boats, Rigby confronted Mr Sunak about small boat crossings. More than 10,000 migrants have arrived in the UK by crossing the Channel in small boats in 2024 – a new record for this stage in the year.
Part of the Tory strategy to cut the number of crossings is the controversial Rwanda policy, which Mr Sunak again vowed would take off in July if he wins the election.

Asked why, if he is so confident flights would take off in July, he didn’t prove this before calling an election, Mr Sunak said “it was the right moment” to go to the polls.
Meanwhile, Rigby outlined how net migration in the past three years stands at 1.9 million people – against 836,000 before Brexit.
With the figure more than doubling since leaving the European Union, Mr Sunak admitted “it’s too high”.
“I’m sure people feel frustrated about that,” he said. “The numbers are too high.”
Starmer distances from Corbyn
Questioned on trust, Sir Keir defended changing previous stances he held, including Labour policies.
He said the “country comes first, party second” and looked back at previous decisions to ask himself if they’re best for the nation, rather than Labour.
Reminded on his claim in the last election that Jeremy Corbyn would make a “great prime minister”, the Labour leader refused to answer directly if he believed that.
Instead, he repeated he was “certain” the party would lose the election in 2019.

What we didn’t know about the leaders
Asked what he fears most about becoming prime minister, the Labour leader said he’s worried about the impact it will have on his family, including his children aged 16 and 13.

Rigby asked Mr Sunak to tell the audience one thing they might not know about him.

He said he’s not as healthy as he appears and has a real sweet tooth. Haribo and Twix are apparently his favourites.
