Excerpts from Friday's agreement by European Union leaders on migration:
1. The European Council reconfirms that a precondition for a functioning EU policy relies on a comprehensive approach to migration which combines more effective control of the EU's external borders. ... This is a challenge not only for a single Member State, but for Europe as a whole.
2. The European Council is determined ... to prevent a return to the uncontrolled flows of 2015 and to further stem illegal migration on all existing and emerging routes.
