The document is a declaration by the leaders of 27 EU member states and EU institutions marking the 60th anniversary of the Treaty of Rome. It outlines four priorities for the future of the EU: 1) a safe and secure Europe with secure borders and effective migration policies; 2) a prosperous and sustainable Europe with a strong single market and sustainable growth; 3) a social Europe promoting equality, inclusion and opportunities for citizens; 4) a stronger global actor promoting stability, security and a rules-based international order. The leaders pledge to work together across levels of governance to achieve these objectives while respecting subsidiarity and being responsive to citizens' concerns.
