Scotland's main party leaders take part in a live debate, hosted by the BBC's Sarah Smith.
Nicola Sturgeon (SNP); Kezia Dugdale (Labour); Ruth Davidson (Conservative) and Willie Rennie (Lib Dems) answered questions.
They were joined by Patrick Harvie of the Scottish Greens and David Coburn from UKIP.
The debate takes place ahead of the General Election on 8 June.
At the ballot box in 2015, the SNP won 56 Scottish seats with the Conservatives, Labour and the Lib Dems winning one each.
Ms Sturgeon says it seems like Ruth Davidson started out opposing Brexit, but in favour of staying in the single market, and now she is opposed to the single market.
"Ruth Davidson does everything Theresa May tells her to," says the SNP leader.
Sarah Smith asks if Ruth Davidson has changed her mind about staying in the single market.
Ms Davidson says she backs Theresa May's push for a free trade deal with the EU members.
The Scottish Conservative leader insists Ms Sturgeon has ignored the votes of the Leavers and is using the Remain voters as a proxy for independence.

When Theresa May formally signed a letter triggering the UK's departure from the EU, in March, the prime minister fired the starting gun on a two-year negotiation process that will have far-reaching implications for British businesses.
Mrs May's claim that "no deal is better than a bad deal" has raised concerns among UK companies that a so-called "hard Brexit" could have a detrimental impact on jobs and investment in the country.
Nicola Sturgeon says people should vote for the SNP as the Tories are pursuing the most extreme form of Brexit.
Ms Sturgeon says if you want to make sure Scotland's voice cannot be ignored then you must vote for her party.
She says this election gives the opportunity to send a message saying Scotland will not be ignored.
The SNP leader adds that staying in the single market is so important to Scotland.
Scottish Greens co-convener Patrick Harvie says Scotland needs a Green voice at Westminster and that the Tories are "hell-bent on a bonfire of regulation".
Mr Harvie says we need to be investing in a sustainable economy to enable everyone to live in dignity and free of poverty.
UKIP's David Coburn says his party is the party of Brexit and only his party is trusted to get the UK out of the EU.
He says the other parties were all remainers.
Scottish Lib Dem leader Willie Rennie says "This is a chance to change the direction of the country" and to turn away from another independence referendum.
Mr Rennie says, by putting a pennie on income tax, the direction of the country can be changed for a brighter future.
Scottish Conservative Leader Ruth Davidson says this election is a massive opportunity for Scotland.
Ms Davidson says the challenges can be met but "not if we are divided".
She says: "Fix our schools don't split up our country."
Scottish Labour leader Kezia Dugdale says she voted to remain in the EU and against independence.
Ms Dugdale says the SNP are "hell-bent" on independence.
The Scottish Labour leader says "reject the Tories" and independence by voting for Labour.
SNP leader Nicola Sturgeon says in the years ahead it will be vital to have strong voices for Scotland at Westminster.
The first minister says a vote for the SNP can halt the cuts and austerity.
She adds that a vote for the SNP will strengthen Scotland's hand against an "extreme Brexit".
BBC Scotland political editor Brian Taylor says the politicians will have prepared both attack and defence.
He says: "Hey its gladiatorial."
BBC Scotland Editor Sarah Smith gets us under way by introducing the Scottish party leaders and Jackie Bird in the spin room.
