Good night. That's the end of tonight's STV Leaders' Debate - catch up on the STV Player if you missed out. There will also be extensive coverage and analysis of the UK General Election on the STV News website.

Referring to the deletion of WhatsApp messages during the pandemic, Cole-Hamilton asks Swinney: "Can you understand why families who used to trust you now feel so utterly betrayed?"

Swinney replied: "I understand the deep sensitivity everyone feels about the Covid pandemic and we all lived through that, and as a government minister I lived through the difficulties and the challenges every day of trying to take the right decisions, particularly where information was developing and emerging about the threat we were facing."

Douglas Ross should be “begging for forgiveness” from the people of Scotland for the “Tory Party damage” of the past 14 years, Sarwar said.

“You shouldn’t be pleading for votes, you should be begging for forgiveness from the Scottish people,” he said.

Sarwar pointed to an increase in mortgage rates, food and energy prices.

The Scottish Tory leader said he would he was not “downplaying the difficult circumstances that are facing people in Scotland, across the UK and indeed in many other parts of the world”.

Sarwar asked Ross: "What achievement over the past five years are you most proud of? Are you most proud of Boris Johnson partying while people were locked away from their families, are you most proud of Rishi Sunak giving billions of pounds of PPE contracts to his pals, are you most proud of Liz Truss' mini budget that crashed the economy or are you most proud of Suella Braverman inciting a riot at the Cenotaph?"

Ross said he was “proud of how this country came together in some of the most difficult periods”.

He insisted he would not defend lockdown parties at Westminster, saying: “I followed the rules to the letter of the law.”

Sarwar told him: “This election is about change, it is about getting rid of the Tories, and Scotland can’t afford five more years of a Tory party government and it can’t afford to miss this opportunity of electing a Labour government.”

The Lib Dems have learned from the “hated” highly protected marine areas (HPMAs) policy in Scotland for a similar proposal from his party for the rest of the UK.

The Scottish Government was forced to drop its push to rid 10% of Scottish waters of human interference after a widespread backlash from rural areas.

Under questioning from Scottish Tory leader Douglas Ross, Alex Cole-Hamilton said: “The UK policy (proposed by the Lib Dems) has actually learned from the mistakes of the widespread and hated highly protected marine areas.”

Cole-Hamilton repeatedly said further details of the policy would be in his party’s manifesto, but said there had been consultation with fishing communities.

Several political correspondents on Twitter have commented on what they deem a cosying up between Cole-Hamilton and Ross.

John Swinney asks Alex Cole-Hamilton: "How on earth can we take the Liberal Democrats seriously on this question of EU membership? Will the Liberal Democrats be committed in the next parliamentary term to returning the United Kingdom to EU membership?'

Cole-Hamilton responds: "Nobody can promise that John, you can't promise that. John, you said at the start of this programme you didn't want a shouting match. 

"There will be an election in the future where our membership of the EU is on the ballot and the Lib Dems will be in the vanguard of that but because of what has happened with the Conservative Party in terms of their damaging, reckless behaviour around the trusted relationships we had with Europe, then that is far, far removed."

Alex Cole-Hamilton asks what Labour's plan is for the NHS in rural areas.

Sarwar responds: "The reality is whether you live in a rural community, an urban community or an island community, there are far too many people stuck on an NHS waiting list - 840,000 of our fellow Scots stuck on an NHS waiting list.

"We've got to have a proper workforce plan, something that's not happened for well over a decade. It's why we have to invest in technology, so we can do faster, rapid diagnosis, particularly remotely."

John Swinney asks Anas Sarwar where £18bn of spending cuts will come from if Labour win the General Election, to which the Scottish Labour responds: "I don't accept there will be spending cuts. We have set out where we will raise extra revenues to both invest in our public services right now, as well as make the investments for the long-term."

First Minister John Swinney has said he is concerned a failure to ensure a just transition away from fossil fuels would create a “industrial wasteland” in the north east of Scotland.

In an exchange where he criticised the Labour position on oil and gas, Swinney said there had to be a managed transition to net zero, likening a failure to do so to the policies of Margaret Thatcher in the 1980s.

“What Mrs Thatcher did when she was in power, was she created an industrial wasteland in central Scotland and we’re still picking up the pieces,” he said.

The danger of the Labour stance, the First Minister told Sarwar, was that “you’re going to do exactly the same to the north east of Scotland”.

Colin Mackay's opening question is about a new YouGov poll that shows Labour is on course for the biggest election victory in history, beating Tony Blair’s 1997 landslide, according to a new YouGov poll.

The poll, using the MRP (multi-level regression and post-stratification) technique and carried out for Sky News, suggests that Sir Keir Starmer’s party is on course to win 422 seats, with the Tories down to just 140.

The Tories would lose 232 seats compared to the 2019 election results, dropping to just 140, according to YouGov’s projection.

This would be far fewer than the previous lowest number of Conservative seats in recent history: 165 in 1997, according to the poll for Sky News.

The MRP poll predicts Labour would win a 194-seat majority, the highest number since Stanley Baldwin won a majority of 208 in 1924.
