The Government has released documents relating to Operation Yellowhammer - its assessment of the impact of a worst-case no-deal Brexit.

MPs won a vote to force the Government to release the documents on Monday.

Only one section of the document is redacted. The rest shows:

'Low-income groups will be disproportionately affected by any price rises in food and fuel'

Disruption at ports will last three months before it starts to improve

Lorries could face delays of up to 2.5 days

As Brits will face immigration checks, there will be delays at airports, train stations and ports

Electricity prices will increase "significantly" to consumers and businesses

Medicines are "particularly vulnerable" to extended delays

It will be harder to prevent and control disease outbreaks

Supplies of fresh food will decrease - there is a risk of panic buying

UK nationals overseas will lose rights and access to services

Protests and counter-protests will take place across the UK - 'there may be a rise in public disorder and community tensions'

Trade with Ireland will be "severely" disrupted with "agri-food" hardest hit

There is a likelihood of clashes between fishing vessels as EU nations fishing vessels will be in UK waters

Care for the elderly services are vulnerable to rising prices and medicine shortages

The document is titled: "Operation Yellowhammer: HMG Reasonable Worst Case Planning Assumptions".

Rosamund Urwin, the Sunday Times journalist who obtained a leak of the same Yellowhammer document in mid August, wrote on Twitter the Government had since changed its name.

She wrote: "This is the same version the Sunday Times had in mid August. However the header of that was different. It said 'HMG Planning Assumptions' then 'Base Scenario'."

The documents are here.

In a letter to Hilary Benn published alongside the document, Michael Gove says that the section redacted has been hidden due to "commercial sensitivity".

He says the Operation Yellowhammer document is "neither an impact assessment, nor a prediction of what is most likely to happen. It describes what could occur in a reasonable worst case scenario, thus providing a deliberately stretching context for government planning to ensure that we are prepared for exit".

In a letter to Tory MP Dominic Grieve published at the same time, Michael Gove sets out the Government's reasons for not replying with the second part of the order from MPs - to release communications between the Prime Minister and No 10 advisers relating to the decision to prorogue Parliament.

He questions the legality of the order, citing other legislation that protects the privacy of such communication, and says it is "inappropriate in principle and in practice, would on its own terms purport to require the Government to contravene the law".

The release of the document came as Prime Minister Boris Johnson was facing furious demands for the immediate recall of MPs to Westminster after the suspension of Parliament was ruled unlawful by Scotland's highest civil court.

In a dramatic judgment, the Court of Session in Edinburgh found ministers had stopped MPs from sitting for the "improper purpose of stymying Parliament".

It said advice given by ministers to the Queen which led to the five-week prorogation was therefore "unlawful and is thus null and of no effect".

The Government immediately announced it was lodging an appeal against the ruling with the Supreme Court, with a hearing set for Tuesday.

Helen Dickinson, chief executive of the British Retail Consortium, said: "The Yellowhammer document confirms what retailers have been saying for the last three years - fresh food availability will decrease, consumer choice will decrease, and prices will rise. This isn't good for the British public and this isn't good for British retailers.

"A no-deal Brexit in November represents the worst possible timing for the retail industry and the consumers it serves. Warehousing availability will be limited as retailers prepare for Black Friday and Christmas, many fresh fruit and vegetables will be out of season in the UK, and imports will be hampered by disruption through the Channel Straits that could reduce flow by up to 60% for up to three months."

The BMA said the "alarming" Yellowhammer document confirmed its warnings about the impact of a no-deal Brexit.

BMA Council chairman Dr Chaand Nagpaul said: "Here we see in black and white the Government warning of disruption to vital medicine supplies, a higher risk of disease outbreaks due to veterinary medicine supply issues, and UK pensioners in the EU being unable to access healthcare from 1 November if there is a no-deal Brexit.

"The warnings around social care providers folding within months of Brexit day are particularly concerning, having a huge impact on our most vulnerable patients and the wider health service in the depths of winter."

In relation to fishing, the Yellowhammer document says up to 282 EU and EEA nations fishing vessels could enter illegally, or already be fishing in UK waters (up to 129 vessels in English waters, 100 vessels in Scottish waters, 40 vessels in Welsh waters, 13 vessels in Northern Irish waters) on day one.

"This is likely to cause anger and frustration in the UK catching sector, which could lead to both clashes between fishing vessels and an increase in non-compliance in the domestic fleet," it said.

On Wednesday, business secretary Andrea Leadsom said that Operation Yellowhammer documents were a "worst case scenario" about leaving without a deal rather than a "prediction".

"I actually do not think that it serves people well to see what is absolutely the worst thing that could happen."

The Prime Minister's spokesman said MPs demands to see Operation Yellowhammer, and messages by Downing Street staff about prorogation were "disproportionate and unprecedented".
