Scotland's Transport Minister, Keith Brown, will make a statement to MSPs in Holyrood this afternoon expressing his concern over the decision to cancel the West Coast Mainline Deal.
FirstGroup was due to take over running the Glasgow to London line in December. The UK Government's u-turn has been estimated to cost taxpayers £40m.
Mr Brown says it is unacceptable that the Scottish Government was given no warning of the decision to scrap the deal after mistakes were found in the bidding process. He said:
The UK Government has ordered two independent inquiries into what went wrong with the West Coast process and has suspended three civil servants.
