<human>:  What is the significance of the Brexit?
<bot>: The Brexit is the process by which the United Kingdom officially withdrew from the European Union. This process began on June 23, 2016 when the United Kingdom voted in a referendum to leave the European Union. The Brexit has caused a lot of political and economic uncertainty in Europe, due to the UK's departure, and the possible implications for other countries in the European Union. In addition, the Brexit has strong implications for the relationship between the UK and the EU, as it will increase the level of tariffs and have a range of implications for the free movement of people.
