The people in the UK have voted to leave the European Union (the EU).
The European Union is a group of 28 countries in Europe that have agreed to co-operate—to all become one group, in many ways. For instance, people in European Union countries can travel, live and work easily in any other EU country. And businesses that are in the European Union can send products back and forth more easily. Nineteen of the EU countries all use the same money–the Euro.
On Thursday, June 23 there was a very important vote.
