The British government has published its 'Operation Yellowhammer' documents - relating to the worst case planning for a no-deal Brexit.
Details of the plan had previously been leaked by The Sunday Times, but have now been published in full following a parliamentary motion demanding the release.
It contains a number of stark warnings, including a possible "rise in public disorder and community tensions".
However, the government has refused to publish documents from senior officials related to the reasons for proroguing parliament - with minister Michael Gove claiming the parliamentary request for such documents was "unprecedented, inappropriate, and disproportionate".
According to the 'Yellowhammer' document - which is dated August 2nd, after Boris Johnson's government took office - it's based on the assumption that "all rights and reciprocal arrangements with the EU" would end on October 31st.
It warns of potential significant disruption at ports and other border posts, while lorries could face maximum delays of up to two-and-a-half days
It warns medicine supply chains would be "particularly vulnerable to severe extended delays".
The document states: "Whilst some products can be stockpiled, others cannot due to short shelf lives - it will also not be practical to stockpile products to cover expected delays of up to six months."
Meanwhile, it's also predicted that "certain types of fresh food supply will decrease" in the worst case scenario.
While this would not cause major food shortages, it would reduce "availability and choice of products and will increase price" - noting there is also a risk of panic buying further exacerbating disruption.
Public water supplies are not forecast to be impacted, but there is a 'low' risk of a failure in the chemical supply chain - potentially impacting hundreds of thousands of people.
The Yellowhammer document also notes that UK nationals would lose their EU citizenship and could expect to lose "associated rights and access to services over time".
Elsewhere, the plan also notes that protests and counter-protests in the UK itself would likely take place, requiring significant police resources.
"There may also be a rise in public disorder and community tensions," it adds.
Other warnings include 'significant' electricity price rises and disruption in law enforcement data sharing between the UK and EU.
Reacting to the release, Labour shadow Brexit secretary Keir Starmer said: "These documents confirm the severe risks of a no-deal Brexit, which Labour has worked so hard to block.
"It is completely irresponsible for the government to have tried to ignore these stark warnings and prevent the public from seeing the evidence."
He called for parliament to be recalled to scrutinise the documents.
Earlier today, Finance Minister Paschal Donohoe confirmed Budget 2020 will be based "on the assumption of a no-deal Brexit" due to the "increasing likelihood" of a disorderly UK exit from the EU.
