Feeling a little lost on Brexit? Never really got your head around it in the first place? Let us walk you through it.
29 March 2019
What is Brexit?
Brexit is short for "British exit" - and is the word people use to talk about the United Kingdom's decision to leave the European Union (EU).
What is the EU?
The EU is a political and economic union of 28 countries which trade with each other and allow citizens to move easily between the countries to live and work (click here if you want to see the full list).
The UK joined the EU, then known as the EEC (European Economic Community), in 1973.
Why is the UK leaving?
A public vote - called a referendum - was held on Thursday 23 June 2016 when voters were asked just one question - whether the UK should leave or remain in the European Union.
The Leave side won by nearly 52% to 48% - 17.4m votes to 16.1m - but the exit didn't happen straight away.
It was due to take place on 29 March 2019 - but the EU agreed to postpone this date. (We will explain in more detail below).
What has happened so far?
The 2016 vote was just the start. Since then, negotiations have been taking place between the UK and the other EU countries.
The discussions have been mainly over the "divorce" deal, which sets out exactly how the UK leaves - not what will happen afterwards.
This deal is known as the Withdrawal Agreement.
What does the Withdrawal Agreement say?
The Withdrawal Agreement covers some of these key points:
- How much money the UK will have to pay the EU in order to break the partnership - that's about £39bn
- What will happen to UK citizens living elsewhere in the EU, and equally, what will happen to EU citizens living in the UK
- How to avoid the return of a physical border between Northern Ireland and the Republic of Ireland when it becomes the frontier between the UK and the EU
A length of time, called the transition period, has been agreed to allow the UK and EU to agree a trade deal and to give businesses the time to adjust.
That means that if the withdrawal agreement gets the green light, there will be no huge changes between the date of Brexit and 31 December 2020.
Another, much shorter, document has also been drawn up that gives an overview of what the UK and EU's future relationship will be in the longer term.
This is the political declaration. However, neither side has to stick exactly to what it says - it is a set of ambitions for future talks.
The deal was agreed by the UK and the EU in November 2018, but it also has to be approved by British MPs.
Have MPs backed the Withdrawal Agreement?
Well, no. They have voted against it three times.
On 15 January they rejected the deal by 432 votes to 202 - the largest defeat for a sitting government in history.
Then on 12 March, after Theresa May had gone back to the EU to secure further legal assurances, they rejected it again.
And on 29 March - the original day that the UK was due to leave the EU - MPs rejected it for a third time by 344 votes to 286.
That means the UK has missed an EU deadline to secure an extension of the Brexit process and leave with a deal on 22 May.
So what happens now?
The key date now is 12 April - the UK will need to tell the EU what it wants to do next by then.
For example, it could ask for another extension.
But if the UK wants a long extension, it faces having to take part in elections for the European Parliament.
Otherwise, the default is that the UK will leave without a deal on 12 April.
Why do people oppose the deal?

There are a broad range of complaints, many of which claim the deal fails to give back to the UK control of its own affairs from the EU.
One of the biggest sticking points has been over what happens at the Irish border.
Both the EU and UK want to avoid the return of guard posts and checks (here's why), so something called the backstop - a sort of safety net - was included in the deal.
What is the backstop?
The backstop is meant to be a last resort to keep an open border on the island of Ireland - whatever happens in the Brexit negotiations.
It would mean that Northern Ireland, but not the rest of the UK, would still follow some EU rules on things such as food products.
The prime minister insists that if all goes as planned it will never be used.
But it has annoyed some MPs, who are angry that the UK would not be able to end it without the EU's permission and so EU rules could remain in place for good.
Other MPs would prefer the UK to stay closer to the EU - or even still, in it.
And others say Northern Ireland should not be treated separately from the rest of the UK.
On 11 March, Mrs May and the EU released a statement, giving added legal reassurances that the backstop plan, if it ever needed to be used, would only be temporary.
Mrs May hoped the statement would persuade her MPs to vote for her deal, but it was still rejected.
So could Brexit actually not happen at all?
It is written into law that the UK will be leaving on 12 April.
The European Court of Justice has said the UK could cancel Brexit altogether without the agreement of other nations, but politically, that's not likely to happen.
What happens if the UK leaves without a deal?
"No deal" means the UK would have failed to agree a withdrawal agreement.
That would mean there would be no transition period after the UK leaves, and EU laws would stop applying to the UK immediately (more on that here).
The government says it is preparing for this potential situation.
It expects some food prices could rise and checks at customs could cost businesses billions of pounds. (Read the government's report here).
It has published a series of guides - which cover everything from mobile roaming on holiday to the impact on electricity supplies.
Here is a list of 10 ways you could be affected by a no-deal Brexit.
