Jackson Carlaw says a hung parliament would be a bad thing.

The Scottish interim leader says public services are currently suffering because the constitution is Nicola Sturgeon's first, second and third priorities.

The first minister and SNP leader points out there has been a material change since the first independence referendum and adds she does not accept the EU referendum result because Scotland voted against it.

Davie Graham asks if a hung parliament, with no single party in overall control, would necessarily be a bad thing.

Ms Sturgeon says she will always be in favour of more powers coming to the Scottish Parliament, but other parties have not really spoken about what so-called "devo max" is.

She adds that she hopes the Tories are not re-elected on Thursday. She poses that it is time Scotland was in a better position than crossing its fingers and hoping for the "least worst option".

"It's not democracy if people are not allowed to change their minds when the circumstances have changed," says Nicola Sturgeon.

I do believe people in Scotland will vote to be independent when given the choice again, she adds.

The questioner Matthew Brickell says he thinks independence is more likely after the "arrogance of the Westminster government" in its treatment of the Union.

"Well you wouldn't expect me to agree with that," says Jackson Carlaw.

The Scottish Conservative interim leader says in each referendum one side has not accepted the outcome which is politically divisive.

He doesn't believe there will be a second independence referendum, citing the once in a generation pledge.

People have seen the economic damage of Brexit and will be put off independence, suggests Scottish Lib Dem leader Willie Rennie.

Matthew Brickell asks if it is inevitable that Scotland will vote for independence if the UK eventually leaves the European Union.

In response to the original question about the level of mistrust, Willie Rennie replies: "It deeply concerns me."

"I want people to believe in the political system as a whole."

Labour's Richard Leonard says his party has attempted to set out how commitments will be paid.

"Part of leadership is listening," he says, adding: "There are times when people are guilty of transposing their own priorities rather than listening to the priorities of the people and the communities we are supposed to serve."

Asked about Jon Ashworth being recorded criticising Jeremy Corbyn, Mr Leonard replies Mr Ashworth says he was winding up a friend of his who is a Conservative.

I'm not sure I have any Tory friends so would not be caught in the position, he jokes.

"I think we live in a much less deferential age," says Jackson Carlaw.

The Scottish Conservative interim leader says the political football should be taken out of the NHS.

He says: "You are best and correct to question everything politicians say."

Nicola Sturgeon says she does worry about the tone and tenor of political debate.

We must focus on the issues and try bring people together, she says.

Ms Sturgeon adds that the difference between her and the three other politicians on the panel is that they all want to tell the people of Scotland what their future is.

Fiona Burton says our country is divided on Brexit but appears to be united in its mistrust of politicians.

Many feel you are all unable to put the needs of the nation above the interests of your own party.

Lib Dem MSP Alex Cole-Hamilton says his party's message is to support Scotland's place in the UK and the EU.

We are the only people speaking for that group of people he says.

This will lead to gains for us on Thursday, he argues.

Scottish Labour Party member Pam Duncan-Glancy says Jeremy Corbyn is "absolutely" a credible leader.

She adds that if the country wakes up with Mr Corbyn as leader on Friday morning "we'll have hope and transformational change".

The alternative, Boris Johnson, is not something the country can tolerate says Ms Duncan-Glancy.
