She did not define precisely how long the expansion may be.
Leaders ultimately coalesced around October 31 - Halloween - as the latest Brexit deadline, averting a potentially disruptive no-deal British departure that would have happened Friday if no extension had been agreed.
At the same time, one should note the purely political nature of this decision: Emmanuel Macron sought a shorter extension and managed to pull out a compromise. All that was needed was ratification from the British and European Parliaments.
"The European Council takes note of the commitment by the United Kingdom to act in a constructive and responsible manner throughout the extension period in accordance with the duty of honest cooperation, and expects the United Kingdom to fulfill this commitment and Treaty obligation in a manner that reflects its situation as a withdrawing Member State", the document continues.
