British political parties have had consistent views on European integration since World War II. Both Conservatives and Labour have approached Europe based on their existing beliefs, with Labour focusing on economic aspects and Conservatives on political ones. The debate has often revolved around sovereignty and the role of the UK government. Different political visions within and outside Europe have influenced Britain's stance on European unions, including the EU, NATO, and EFTA. Europe's importance in British statecraft has been intertwined with domestic issues, shaping the country's foreign policy decisions.
