Seminar paper from the year 2020 in the subject Economics - International Economic Relations, grade: 1,3, University of applied sciences, Düsseldorf, language: English, abstract: This essay deals with the withdrawal of the United Kingdom (UK) from the European Union (EU) and the resulting consequences for German companies which have business relations with the UK. The process and the reasons for Brexit will be explained chronologically followed by various consequences for German companies. The result of the referendum in June 2016 makes the UK the first country in the history of the EU to leave the association of states. The Brexit process and the associated contract negotiations took several years until the UK finally left the EU on 31.01.2020. However, many aspects - such as trading conditions - have still not been fully negotiated and there will be a transitional period until the end of the year. Since Germany and the UK are major trading partners for each other, there are consequences for German companies in various areas. In addition to the impact on trade, there may also be implications for value chains, employees or even corporate financing.
