“If ypu think this move is proof of financial mismanagement, then I am afraid TheresaMay is the culprit.”
Let’s leave aside the argument over who is responsible for awarding the franchise, whether the Scottish Parliament or Westminster (but it is the Scottish Parliament as transport is a matter devolved to them):

But let’s assume, incorrectly, that it is Westminster. The Scottish rail franchise has been in the hands of Abellio since 1st April 2015 with the franchise having been awarded in October 2014. At that time Mrs May was the Home Secretary and I didn’t realise that the holder of that office had the responsibility for letting rail franchises anywhere in the UK, let alone in Scotland. But let's not allow two incorrect assumptions undermine a bit of Tory bashing.
