On Thursday, the UK voted to leave the European Union.
Going into the day, exit polls hinted at a narrow victory for the Leave campaign, with the eventual results showing a 52% majority of voters favouring Brexit - a total of over one million votes.
Following the outcome, there will now be a period of negotiation before Britain leaves the EU. This is because of something called Article 50, which has been mentioned a lot over the past 24 hours.
Article 50 is part of the of the 2009 Lisbon Treaty - the document which governs membership of the EU - and it states that Britain and the other 27 member states of the EU are allowed up to two years to negotiate an exit from the union.
David Cameron resigns
In the wake of the result, Prime Minister David Cameron handed in his resignation. Cameron was a vocal advocate of the Remain campaign, and declared that “fresh leadership was needed”.
Speaking outside 10 Downing Street, Cameron said: “The British people have voted to leave the European Union and their will must be respected.
“The will of the British people is an instruction that must be delivered.”
The Conservative leader has announced he’ll leave his post by the time of the party conference, which will take place in October.
It will then be up to the new Prime Minister to enact Article 50 and begin the negotiation period as Britain commences its exit from the European Union.
