EU budget summit ended without agreement on Friday following a stand-off between wealthy "frugal" member states and other countries.
The so-called "frugal four" of Denmark, Austria, Sweden and the Netherlands said they would not accept a budget of more than 1% of the bloc's GDP.
France's Emmanuel Macron said it showed "we don't need Britain to show disunity".
Brexit has left a 75bn ($81bn; £63bn) gap in the seven-year budget.
The UK was a net contributor to the EU.
