Last year a former senior aide to the UK Brexit department revealed that the UK government commissioned secret analysis on the impact of Brexit.
Now we know that a detailed impact assessment does exist.
According to Buzzfeed, the leaked UK government analysis suggests every part of the economy in every part of the country would suffer.
Indeed their findings are roughly in line with Scottish Government analysis published earlier this year - which at the time was dismissed by Tories as ‘scaremongering’.
The UK government wanted their analysis to remain secret. But the cat is out the bag - and now they need to publish it in full.
