John Swinney is asked by Tory leader Russell Findlay about the soaring costs of the new Barlinnie Prison
Scottish Labour leader Anas Sarwar asks if the Scottish government will end its "ideological block" on nuclear power
Rent controls are raised by Scottish Greens co-leader Lorna Slater
Other issues raised by backbenchers include The Promise - made to children in care, the Rosebank oil field decision and Grangemouth redundancies
The Scottish Tory leader accuses the SNP of releasing thousands of criminals before their time.
Findlay argues this will lead to "a billion pounds and more crime".
The first minister points out the new prison will accommodate more than 1,340 prisoners.
Swinney says he expects his ministers to take rational decisions that protect the public purse.
Findlay says John Swinney thinks he's "building either a luxury resort or a nature reserve".
The Scottish Tory leader outlines some of the expensive details of the new prison and argues this is "nonsense". He calls for a prison "at minimum cost to taxpayers not maximum benefit to prisoners".
The first minister hits back, saying Findlay's tone is "reprehensible and despicable".
Swinney insists he wants to make sure there is a replacement prison that is safe and secure.

We now know the replacement for Barlinnie prison will cost nearly £1bn, almost double the previous estimate.
Justice Secretary Angela Constance confirmed a cost of £998.4m for HMP Glasgow in a letter to the criminal justice committee. She also stated it will open in 2028, three years later than originally planned,
The 1,344 capacity prison in the Germiston area will add 357 places to the overall prison estate, in an attempt to solve problems with overcrowding plaguing Scotland's jails.
Constance said the "significant increase" in costs - from a previous estimate in 2022 of £400m - was due to wider increases across the construction sector.
"It's essential that we replace HMP Barlinnie," John Swinney replies.
The first minister explains that the project is different from the one that was estimated and "the government will monitor and control the cost carefully as the project takes its course".
The Scottish Tory leader tells the chamber the SNP government previously told the public it would cost £100m to build HMP Glasgow, but yesterday a "bombshell was dropped on taxpayers", with the cost now £998.4m.
"That's just shy of £1bn," he says.
Russell Findlay bets it will only go higher.
"Does a billion pound Barlinnie really represent good value for Scotland's taxpayers?", he asks.
John Swinney is sitting ready and poised for the fray, as Russell Findlay gets to his feet to begin this week's political jousting.

It’s one of those weeks where there isn’t necessarily a big issue which all of the leaders will be champing at the bit to ask about. But there are plenty of issues falling into each party’s core areas of interest which could crop up.
There are some justice stories which Russell Findlay could pick, if he opts to remain in his comfort zone – the soaring cost of the new Barlinnie prison being the most obvious.
There’s the question of how data from school sex surveys is being used, albeit there was an urgent question about that yesterday so it may have had its moment.
Labour have previously campaigned on homelessness, and may home in on this week’s headlines about a record number of children being in temporary accommodation.
The Greens have a question this week, and frequently do use them to ask about Donald Trump, with fresh questions swirling about relations with the US President in light of his pronouncements about Gaza.
One green topic which absolutely will come up is last week’s legal ruling about the Rosebank and Jackdaw oil and gas fields, because Tory MSP Douglas Lumsden has a question tabled on it – sure to feature his party’s position about workers in the north east being left behind.
Talking of fossil fuels, the latest steps towards the closure of the Grangemouth oil refinery are also likely to come up at some point.
So there are plenty of options – meaning John Swinney will have had to a mountain of prep work to make sure he has answers ready for every eventuality.
It's been another busy week at Holyrood with a number of stories catching the eye.
The SNP's first budget since throwing the Greens out of government will be approved with the support of at least four parties. Earlier this week it passed its first Holyrood vote.
We learned that councils will have to make "difficult decisions" to cover a £100m funding gap arising from the UK-wide increase in employer National Insurance.
Some workers at the Grangemouth refinery were sent redundancy letters by their employer Petroineos.
Meanwhile, Norwegian energy giant Equinor's chief executive said he was confident that Rosebank - the giant new oil field - would go ahead.
It emerged that the replacement for Barlinnie prison will cost nearly £1bn, almost double the previous estimate.
And more than £34m has been spent developing plans for five delayed NHS treatment centres which are meant to deal with a backlog of operations.
