@Walter Hinteler,
The government is gaming the use of drastic powers to halt unrest if the UK crashes out of the EU.
A source told the The Sunday Times: "The over-riding theme in all the no-deal planning is civil disobedience and the fear that it will lead to death in the event of food and medical shortages."
The newspaper quoted another source as saying that planners were using the disruption caused by the volcanic ash in Iceland during 2010 as a model for possible disorder.
"Although there is nothing that can replicate the scale of chaos threatened by a no-deal Brexit, which will be about a thousand times worse than the volcanic ash cloud crisis, this is about the closest example we have in modern British history.
"The only other thing that would be comparable would be something like a major Europe-wide war."
