The European Union is today a political and economic entity which controls a single market located mainly in Europe, exploiting the euro as currency unique uniting the vast majority of its members. The market shared by all members of the European Union offers free trade in goods and services as well as a common external tariff. It could be argued that the European Union would not have been able to see its current influence without the introduction of the euro. Speaking about the advantages of the euro, we can cite the elimination of exchange rate problems, the creation of a single financial market, ensuring price stability, low interest rates and also being a political symbol of unity and commitment to the Union. Today, the Euro is the second largest reserve currency in the entire world, which speaks volumes about its value on the global market. UK domestic policy towards the Euro: However, many countries have not yet adopted the Euro and have remained incredulous about it. Two countries that fit this example are the United Kingdom and Denmark. The United Kingdom's reluctance to adopt the euro began with its non-participation in the Maastricht Treaty signed in 1992 by all members of the European Community and which led to the creation of the euro. Within the Conservative Party, John Major, then British Prime Minister, was considered “pro-euro” because he pledged to keep Britain “at the very heart of Europe”. However, while his government approved the treaty, he faced strong antagonism in the House of Commons, consisting mainly of the so-called Maastricht rebels, members of his own Conservative Party rather than the Labor opposition. The approval was rejected and Major's authority in Parliament...... middle of paper......with the dollar. He also points out that joining the euro will increase inflation rates in the country, as European inflation rates are currently higher than those in Britain. On jobs, Browne believes that joining the euro would destroy British jobs and repel foreign investors, as it would be a profound shock to the economy and reduce Britain's efficiency in the business world. It would no longer be the country which would have both access to the European market and to a distinct and secure currency, closely linked to the dollar. Tony Blair's government has heard widespread predictions that multinational companies will look to do business elsewhere if Britain joins the euro. Even the simple costs of retraining staff, purchasing new machinery and new accounting systems would impose a burden on the UK's small businesses when the national currency changes..
