Leaders of France, Germany, Italy and Spain are to meet in Versailles on Monday, as Europe prepares to mark the 60th anniversary of the Treaty of Rome, which laid the foundations of the European Union.
EU reform is expected to top the meeting's agenda, with member states deeply divided over issues including a debt crisis, immigration and Brexit.
The Treaty of Rome was an international agreement that led to the creation of what was then called the European Economic Community. It was signed on March 25, 1957 by Belgium, France, Italy, Luxembourg, the Netherlands and West Germany.
The treaty proposed the creation of a single market for goods, labor and services, and is considered one of the most important treaties in the modern-day European Union.
