Although Boris Johnson has agreed a revised deal with the EU, the possibility of a no-deal Brexit has still not been ruled out.What is a no-deal Brexit?
Overnight, the UK would leave the single market and customs Union - arrangements designed to help trade between EU members by eliminating checks and tariffs (taxes on imports).The Brexit Party gained The Most MEPs in May's European elections, on a no-deal platform
No deal also means immediately leaving EU institutions such as the European Court of Justice and Europol, its law enforcement body.
Membership of dozens of EU bodies that govern rules on everything from medicines to trade marks would end.
And the UK would no longer contribute to the EU budget - currently about £9bn a year.
After Mrs May's deal was defeated, the Brexit deadline was extended to 31 October.
To avoid a no-deal Brexit at the end of October, the UK government must pass the Brexit divorce plan into law, obtain another extension from the EU, or cancel Brexit.
Mr Johnson was forced to write a Brexit extension letter to the EU after MPs failed to approve a Brexit revised deal by 19 October.
However, the deadline will only be extended if all The Other EU members agree to one.
But some politicians support no deal and say any disruption could be quickly overcome.What would it mean for trade?
Under a no-deal Brexit, there would be no time to bring in a UK-EU trade deal.
Trade would initially have to be on terms set by the World Trade Organization (WTO), an agency with 162 member countries.
If this happens, a type of tax known as a tariff-ill apply to most goods UK businesses send to the EU. Many companies worry that could make their goods less competitive.
Trading on WTO terms would also mean border checks for goods, which could cause traffic bottlenecks at ports, such as Dover.
No deal would also mean the UK service industry would lose its guaranteed access to the EU single market.
That would affect everyone from bankers and lawyers to musicians and Chefs .Protests have been held against the possible return of a hard border in Ireland after a no-deal Brexit What about the Irish border?
No-one really knows what will happen at the Irish border if there's a no-deal Brexit on 31 October.
In theory, border checks will be needed as soon as the UK leaves the single market and customs Union .
However, neither the UK or Irish governments have said they are willing to install border posts.What about the 'divorce bill'?
That was widely believed to be about £39bn, although delays to The Exit date mean some of it has already been paid and put it at about £33bn.
But opinion is split on what happens if the UK refuses to pay and there's a possibility the UK could end up in an international tribunal.
Individuals could be affected in all sorts of ways.
For example, if the pound falls sharply in response to no deal and there are significant delays at ports, like Dover, it could affect The Price and availability of some foods.
There are also concerns over potential shortages of medicines.
EU citizens in the UK can apply for settled status, allowing them to remain even if there is a no-deal.
UK expats in the EU are advised to register as residents of the country They Live in, although no deal could make moving across borders more difficult.
Travelling with pets will become.
And European Health Insurance Cards (EHIC).Are preparations under way?
Most economists and business groups believe no deal would lead to economic harm.
For example, The Office for Budget Responsibility - which provides independent analysis of the UK's public finances -
To cushion some of the impact, the government is looking at what might happen in a worst-case no-deal scenario. This includes:A section of the M20 had been reserved exclusively for lorries, as part of no-deal Brexit plans
A week after taking office, Mr Johnson pledged an Extra £2. 1bn specifically to prepare for leaving the EU without a deal.
Prior to this, the government led by Mrs May had Promised £4. 2bn to prepare for a range of Brexit scenarios.
Businesses have been encouraged to prepare by stockpiling in case supplies are disrupted.
Supporters of no deal say some of the risks have been exaggerated and that have proven unfounded.
