A group of Member States decides to cooperate much closer on defence matters, making use of the existing legal possibilities. This includes a strong common research and industrial base, joint procurement, more integrated capabilities and enhanced military readiness for joint missions abroad.

Several countries move ahead in security and justice matters. They decide to strengthen cooperation between police forces and intelligence services. They exchange all information in the fight against organised crime and terrorism related activities. Thanks to a joint public prosecutor’s office, they collectively investigate fraud, money laundering and the trafficking of drugs and weapons. They decide to go further in a common justice area in civil matters.

A group of countries, including the euro area and possibly a few others, chooses to work much closer notably on taxation and social matters. Greater harmonisation of tax rules and rates reduces compliance costs and limits tax evasion. Agreed social standards provide certainty for business and contribute to improved working conditions. Industrial cooperation is strengthened in a number of cutting edge technologies, products and services, and rules on their usage are developed collectively.

Further progress is made at 27 to strengthen the single market and reinforce its four freedoms. Relations with third countries, including trade, remain managed at EU level on behalf of all Member States.
