The document discusses Brexit, which refers to the United Kingdom's decision to leave the European Union. A referendum was held on June 23, 2016 where 52% voted to leave the EU. The UK wanted to leave because they felt they paid too much into the EU and received too little in return, and there was excessive migration that caused unemployment among UK citizens. Some problems that need to be resolved as a result of Brexit include importing fresh food and preventing a hard border between Ireland and Northern Ireland.
