Brexit negotiations involved two parties, the UK and the EU. Brexit would signify economic losses for all Member States involved, but the UK would be the most affected. The UK could lose access to a market of 500 million people and face tariffs and regulatory barriers to trade. The free movement of people could also be rejected, and the UK would have a weaker position when negotiating bilateral deals with the EU. Brexit would limit trade with other EU members, leading to food shortages, inflation, and lower standard of living for UK residents.
