It's a Friday afternoon, it's unseasonably warm and there's a Royal Wedding on.

So of course the Tory government has shovelled out 29 drastic warnings about Brexit.

You could be banned from using Netflix and Spotify on holiday, the Eurostar will be under threat, lights could go out in Northern Ireland and race horses will be trapped in Britain if we leave without agreement on 29 March 2019.

That's not to mention confirmation we will lose SEVENTY trade deals around the world.

Today's is the fourth tranche of papers warning of the consequences of No Deal, and takes the total issued to 104. View the first, second and third tranches on Mirror.co.uk.

The warnings were issued today just as the odds of No Deal grew greater, with a standoff between Downing Street and Tory Brexiteers.

Last night Theresa May summoned her inner circle to discuss plans for a "backstop", a backup plan to avoid a hard border in Northern Ireland.

The plan involves, essentially, keeping the whole UK in an EU customs union for a "temporary" period after the date of Brexit.

Boris Johnson says this would render us an "EU colony" because it would stop the UK signing trade deals around the world.

Such a "backstop" had been set to end in December 2021. But Downing Street today refused to rule out the possibility of there being no fixed end date.

Mrs May will try to persuade 27 EU leaders to back her plan at a crucial summit next Wednesday.

But there's still no agreed plan, and the odds of No Deal are ticking closer.

So without further ado... here's what the government says will happen if that's the case.

Biggest No Deal Brexit warnings that affect you

You could be barred from using Netflix and Spotify on holiday

Britons could be barred from accessing their accounts for Netflix, Spotify and other online entertainment while travelling to EU states if there's a no-deal Brexit.

Under the EU-wide "portability regulation", which took force in April, citizens can access accounts set up and based in one country while visiting other member states.

But the technical notice said: "The portability regulation will cease to apply to UK nationals when they travel to the EU.

"This means online content service providers will not be required or able to offer cross-border access to UK consumers under the EU Regulation.

"UK consumers may see restrictions to their online content services when they temporarily visit the EU."

Eurostar trains face major disruption - and you should get insurance and flexible tickets

Eurostar services could be suspended in a no deal Brexit, it's been suggested.

International train passengers - including the Eurostar - have been told to make sure they have "insurance and ticket terms and conditions" that are "sufficient to cover possible disruption".

That implies passengers should buy FLEXIBLE tickets - not the fixed cheap ones that are popular for their low cost.

The UK will need bilateral deals with France, Belgium and the Netherlands to ensure international trains keep running.

Without such a deal, Britain has proposed recognising EU operator licences until March 2021 to ensure services can continue. But UK operators would have to reapply with the EU.

Former Transport Secretary Andrew Adonis said: "This no deal notice seems to be saying that the vital train link between Britain and Europe could be severed.

"This will hurt thousands of travellers and businesses who want to trade with the continent. Brexit will bring about travel chaos."

Northern Ireland faces electricity blackouts

Northern Ireland will be forced to take drastic measures to stop the lights going out.

A worst-case No Deal Brexit would scupper the all-island electricity market shared by Northern Ireland and the Republic - leaving it "without any legal basis".

This would make both markets "less efficient, with potential effects for producers and consumers on both sides of the border," the government warns.

And it "may be necessary to seek additional [legal] powers to preserve security of supply."

To stop the lights going out, Northern Ireland would have to take more electricity from British power stations through an "interconnector" running under the Irish Sea.

But Northern Ireland's Transmission System Operator "may need to rely on fall-back arrangements" to ensure power keeps flowing, the government warns.

That is why, even if there's a no deal, the government will "take all possible measures" to keep the all-island market running.

Dustin Benton of Green Alliance warned: "Any emergency action to keep the lights on, both in Northern Ireland and across the rest of the UK, would likely be highly polluting and expensive."

Package holidaymakers could be left stranded if their firm goes bust

Package holidaymakers could be left stranded with no legal protection if the firm they booked with goes bust.

Currently Brits have "insolvency protection" if they book with a package holiday provider that's based anywhere in the EU.

But in a No Deal Brexit, that protection would only apply if the firms are "targeting" the UK market. That means those booking with, say, a cheaper Spanish firm online that has no UK presence could be unprotected.

Even if the UK government could act, in practice it will be much harder to take enforcement action against foreign firms because other countries will no longer recognise UK courts.

You'll lose rights to take action over dangerous products

The documents reveal the same problem - UK courts not being recognised - will strip Brits of their consumer rights for EU goods bought online.

Alex Neill of consumer group Which? warned: "A no-deal Brexit would massively weaken people's rights to take action when they purchase faulty or dangerous products from outside the UK.

"The Government's advice that we all become experts in international consumer law is hopelessly unrealistic.

"Securing a good deal with the EU is vital to ensure that Brexit doesn't result in a bonfire of consumer rights and protections.”

And finally... your regular caviar parties are doomed!

Awful, terrible news for the establishment.

Caviar imports will be snarled up or stop completely in a No Deal Brexit.

Sturgeon eggs join snowdrops, orchids and reptiles in 'endangered species' that would need import and export permits to cross an EU border.

You'd only be allowed to bring in 125g of caviar for personal use.

A tragedy.

And the biggest that'll affect the business world

British race horses could be banned from Ireland

All British horses would be banned from travelling to the EU under a worst case No Deal Brexit. This would include racecourses in Ireland.

Currently breeding, competition and racehorses can be taken to the Continent with a 'horse passport' and a health certificate or vet's approval.

If there is no Brexit deal, the UK would have to apply to be listed as a "third country". This would allow horses to travel, but force owners to obtain new documents and blood tests costing up to £500 extra.

If the UK is not accepted as a third country, horses would be unable to travel from the UK to the EU at all.

Fishermen face being barred from EU and international waters

The Department for Environment made clear that the UK will leave the Common Fisheries Policy when it quits the EU.

Non-UK registered vessels will no longer have automatic access to British waters - and UK vessels will not have automatic rights to fish in EU waters.

Except in cases of distress, British boats will lose their automatic right to land fish in any EU port.

And they will have to notify their intention to visit and submit to inspections of their catch.

UK-registered vessels could lose their right to fish in international waters covered by Regional Fisheries Management Organisations (RFMOs) during the estimated six months it will take for Britain to rejoin them as an independent coastal state.

Tonnes of waste could pile up

Just days after a human body parts mountain emerged, Britain could be facing a huge pileup of waste as it becomes more difficult to export it to the EU.

Our waste exports to Poland have soared 31% to 11,899 tonnes in just four months, according to Greenpeace, after China banned "foreign trash".

But if there's no Brexit deal, this will be slapped with a tangle of new red tape.

Currently UK waste exporters only need permission from the country they are sending to.

Without a Brexit deal, they would need to submit a "duly reasoned request" to EU authorities.

This request would have to explain why the UK "does not have and cannot reasonably acquire" waste disposal facilities in its own country.

EU websites could be blocked in the UK

EUaarrrrggghhh!

UK citizens could be blocked from some websites based in EU states if there's No Deal.

Under the EU Geo-Blocking Regulation that takes effect in December, businesses and traders are prohibited from discriminating against citizens purchasing good and services online based on their nationality or place of residence in the EU.

However, a technical paper said that in the event of no agreement being reached before the UK leaves the European Union, the regulation would "cease to have effect" in UK law.

UK traders wishing to operate within the EU would still have to abide by the regulations, however.

Pedigree horses, cattle, sheep and pigs will lose EU recognition

Breeders of pedigree horses, cattle, sheep, pigs and goats will lose their automatic recognition in the EU if Britain leaves without a deal.

Recognised UK breed societies and breeding operations will no longer be automatically entitled to enter animals into breeding books in the EU or extend breeding programmes onto the continent.

The Department for the Environment said that such operations would have to apply to the European Commission for certification that they meet EU rules.

However, EU-recognised breed societies and operations will "continue to have access to the UK in the same way as they do now".

And last but not least... we'll lose 70 trade deals around the world

This is enormous (

We knew this one already. It's the biggest impact by far. But seeing it written down is quite something.

The UK will lose free trade agreements with more than 70 non-EU countries around the world if it leaves without a deal.

The countries - which account for 12% of ALL the UK's trade - are covered by around 40 agreements that were negotiated through the EU.

The Department for International Trade (DIT) said: "In the event of a 'no deal', EU trade agreements will cease to apply to the UK when we leave the EU."

DIT said that, in its preparations for Brexit, it wants new bilateral deals with the 70 countries which are "identical or substantially the same" to those we are giving up.

But it warned companies that, even if such deals can be reached, there may be "practical changes" to the way trade takes place.

And it confirmed that if these are not in place in time for a no-deal Brexit, exports and imports will be slapped with eye-watering tariffs under World Trade Organisation rules.

Ian Wright, chief executive of the Food and Drink Federation, warned UK producers could be abandoned as other countries change their suppliers.

“UK exporters of meat, fish and dairy would face further labelling burdens, and have to make immediate and costly changes to produce in order to remove EU health marks,” he said.

"Exporters of fish would also require a catch certificate for each consignment and fish coming into the UK would need a certificate to be submitted three days prior to the shipment arriving at port.

"The limited timeframe for such changes and the accompanying administrative hurdles further threaten the success of UK export sales to the EU, our largest export market."
