[LONDON] No deal was reached between British Prime Minister David Cameron and European Union president Donald Tusk Sunday in talks to agree changes to Britain's membership of the bloc ahead of an in-or-out referendum.
"No deal yet. Intensive work in next 24 (hours) crucial," Mr Tusk wrote on Twitter following a working dinner in Mr Cameron's Downing Street office in London.
The EU president has "agreed to another 24 hours of talks" before publishing a draft of an agreement, Mr Cameron wrote on the site.
A senior government source had said that Mr Cameron would press for an immediate post-referendum ban on European Union migrants from claiming benefits such as income top-ups for low-paid workers until they have paid into the British system.
Mr Cameron has vowed to secure reform in four key areas to address the concerns of British people who doubt the benefits of EU membership, before campaigning to remain within the 28-member bloc in a referendum due by 2017.
An EU source said that "some progress" had been made during the meeting but that there were "still outstanding issues".
