evidence: More recently, in 2007, the two countries came up with plans for reintroducing border controls. If the plans had been successful, then it would have meant the end of the Common Travel Area between the two areas. However, the proposition raised significant outrage from all sides and eventually led to the abandonment of the proposals in 2011 and the subsequent renewal of the "de facto" agreement. That year, December 20, 2011, was the first time that the UK and Irish authorities officially agreed on the maintenance of the border. Data shows that approximately 177,000 lorries, 1,850,000 cars, and 208,000 vans cross the border every month. Additionally, about 30,000 people cross the border on a daily basis for work. [...] The United Kingdom voted to leave the European Union (EU) on June 23, 2016, commonly referred to as Brexit. This decision will mean that Northern Ireland is no longer part of the EU, and will, therefore, complicate the Ireland-United Kingdom (Northern Ireland) border since the free movement agreements in the EU only applies to members of the EU. However, representatives from the EU, the Irish government, and the UK government have all stated that no party wishes to have a hard border between the UK and Ireland. Aside from trade and immigration, health issues have also been raised.
