John Swinney is answering FMQs after announcing plans to extend the scrapping of peak ScotRail fares for another three months.
The First Minister met staff at Edinburgh Waverley when the Scottish Government confirmed that the trial introduced by Humza Yousaf will run until September.
He faces questions from MSPs ahead an announcement from the justice secretary on Scotland’s prison population.
That comes after Scotland’s chief prison inspector said “emergency measures” will need to be taken to reduce the number of prisoners in Scotland amid a reported surge in numbers.
Another ministerial statement will take place later to update Parliament on the prosecution of Post Office Horizon victims in Scotland.
Swinney could also face questions over his Government’s decision to declare a national housing emergency.
